Scoring Record
Every daily edition publishes four predictions, each with a weight, a named falsifier and a hard close date no more than seven days out. Each is graded 0–10 once its window closes, and the running record is recomputed and printed in the edition that grades it. This page reports that ledger. It does not keep a second one.

As printed in the edition of 8 September 2026. A score of 6 or better counts as a hit. A mean below 5 means the calls read the world worse than a coin toss would have.
The figure that differed from the letter now matches it, and the fault is closed.
This page carried 5.09 for form since the rebuild while the edition of 1 September printed 5.10. The gap was not a dispute about the record; it was that the edition had taken the previous day's anchor and added the day's grades, which is more precise and which no reader can reproduce, because that anchor is itself rounded. The stated method is to difference two published anchors and nothing else. The edition of 2 September computed it that way, so the letter and this page now return the same number by the same route, and a reader can check it with the two anchors printed in both.
Form, by grading period
Bars run 0 to 10; the grey line marks 5. Hatched bars rest on fewer than ten predictions and should not be read as form. Blocks are grouped by the date a prediction was graded, not the date it was written — see the note below on why that change was made.
A new block opened today and stands at 5.50 across four, which is too few to read.
The block before it closed on Monday at 6.40 across twenty, on grading days of 5.50, 6.75, 7.25, 6.25 and 6.25, and it remains the strongest full block this page holds. The new one will stay hatched until it reaches ten predictions, and a first day at 5.50 says nothing about where it settles: the block it follows opened at 5.50 as well. Block close dates are derived from the count rather than named in advance from the calendar, a change made yesterday after this page named one and got it wrong.
The most recent board, graded 8 September
Hit7Nothing is admitted for hearing. Continuity, priced 30.
Hit6The condemnation stays a condemnation. Continuity, priced 26.
Hit7Still no formal complaint. Continuity, priced 24.
Miss2Payrolls stay weak. Continuity, priced 20.
Board of 8 September, mean 5.50 across four, three hits and one miss. All four belong to the panel of 1 September, and all four are continuity propositions, the first board carrying the change-or-continuity flag that now replaces the retired panel rule. The miss is the largest single-call loss this page has recorded in a fortnight: a threshold of one hundred thousand jobs, priced at a standalone of eighty-eight, against a first print of 162,000. The hit graded at six is the one worth a reader's attention, and it is the subject of the section below.
The pattern is now measured, and it is the most important thing on this page
Sort every prediction by what it asks. A continuity proposition asks whether a state of affairs will carry on. A change proposition asks whether somebody will do, say or publish a new thing.
The count measures consecutive boards on which both kinds of proposition appeared and continuity outscored change. It stands at ten, and a seventh board has passed without moving it, because no board from 2 September onward carried a change proposition to compare against. From 7 September the count is no longer computed board by board. Every prediction is flagged as change or continuity in the edition that publishes it, and the two are compared by mean grade across a rolling window of forty finalised predictions, which is about ten days of panels. The rule that required each panel to carry at least one change proposition is retired, and why it had to go is set out under the fifth of the known faults below. The count stays paused while the new window fills, but with a fill date rather than indefinitely: the first reading on this basis falls around 14 September. Twenty-eight predictions are now flagged, twelve continuity and nine change, with three still to set from the panel closing tomorrow. The board of 8 September was four continuity propositions at a mean of 5.50, which is the first entry in the new series.
Two boards have made the same point and a third could not extend it. On 3 September, three of four asked whether an institution would carry on doing or not doing something and all three held; the one that failed asked whether a number would stay on one side of a line. On 4 September the split repeated exactly: the corridor, the crossing and the export ban held, and the only failure was again a price against a threshold. The board of 5 September added nothing, because nothing on it failed. The board of 6 September broke the pattern in a way the finding did not anticipate: three institutional continuities held, and the proposition that failed was also institutional — but it failed on its own drafting rather than on the world. The board of 7 September then ran against the distinction outright. The two propositions resting on numbers and official findings both held — a drought status and a sanctions list — and the one that failed was institutional in the purest form available, a government declining to acknowledge strikes, and it failed on the world. Two observations support the distinction, one was lost to a drafting fault, and one now contradicts it. It is printed from today as a hypothesis with an exception rather than as a finding.
The measure this page still owes its readers is a baseline.
A lifetime mean of 5.10 and a hit rate of 49.1 per cent are uninterpretable on their own. The question a sceptical reader should ask, and which this page has never answered, is what a desk that simply predicted continuity every time would have scored on the same panels. If that number is close to 5.10, the analysis is adding nothing and the record is measuring the format rather than the forecasting. If it is well below, the calls are earning their place.
Computing it requires one row per prediction with a change-or-continuity flag, which this page has never held; it carries block anchors, not individual grades. That flag starts today, written at publication rather than reconstructed afterwards, and the twenty-eight predictions already open are being flagged from their published wording where that wording is unambiguous. The same flag produces both this baseline and the counter above, which is the whole reason for adding it. On the open predictions filling the window as they close, the first reading falls around 14 September. It will be published whichever way it comes out.
Four boards, four sentences, and the fault returning in this desk's favour
The dominant fault on this record through the first week of September was not forecasting. It was drafting, and four consecutive boards turned on it. The board of 7 September did not. The board of 8 September did, and this time the wording rescued a proposition rather than sinking one, which is the case a reader should discount hardest.
The proposition held that a condemnation of settler violence would stay a condemnation. Inside its window the Israeli prime minister was reported to have ordered around a hundred outposts dismantled, three settlers were arrested over the attack that prompted the condemnation, and two courts issued orders. The published falsifier required something narrower than any of that: a measure restricting settler entry to a named Palestinian village. None was announced, so the call scored. It was graded at the floor of a hit and the thesis is recorded as refuted, because the alternative — grading on what the desk meant rather than on what it published — is the fault this page spent a week writing rules against. The narrowing that made the proposition gradeable on 1 September is what let it outlive the events it was written about.
On 4 September a threshold was lost by one tenth of one cent, on a series that publishes to three decimal places against a line written to two. On 5 September a proposition survived on the single word naming, while the military activity it was really about escalated around it. On 6 September a prediction was named for one country and specified for any, and had to be graded on the specification because choosing the narrower reading afterwards would have meant taking whichever half scored better. On the same panel, a falsifier abbreviated its object to any change of date, and a date other than the intended one duly changed.
Two of those four were decided against this desk and one was decided in its favour on a technical reading. That is the point. A record that can be moved by where a decimal falls or whether an adjective sits in the heading or the sentence is measuring sentence construction alongside judgement, and a reader has no way to separate the two from the score alone.
Two rules were put in force on 6 September. The actor is named in the operative sentence and not only in the heading. And a falsifier restates its object rather than abbreviating it. Both are narrow, both are checkable before publication, and neither would have been written down had the boards not been graded in public.

Twenty-eight predictions open, every one with a close date inside seven days of the edition that made it. The panel of 1 September closed today and has been graded; the panel of 8 September takes its place. Nothing on this page waits longer than a week to resolve. Long-horizon calls from special editions are held on a separate ledger and graded on their own dates; they are excluded from the figures above. One prediction from 18 August remains carried rather than graded, because the record that would settle it is contested and this desk does not grade a contested record on the convenient reading of it. Two predictions on the schedule above have met their settling observation already, and neither has been closed early. The call of 2 September that at least one Israeli would be arrested or charged over the settler attack on Qusra of 29 August met it on 3 September, when police announced an arrest; two further arrests followed on 6 September. It will be graded tomorrow. The call of 6 September that Russian strikes on Kyiv would resume after the stated halt expired met it overnight, when strikes resumed and two people were killed; it will be graded on 13 September. Both were disclosed while their windows were open rather than argued at the close.
The retired chart
The weekly bar chart this page replaced is preserved, unrevised, at the archived Weekly Accuracy Chart. Weekly means for 1 June to 2 August remain there, together with the audit notes recording every correction and withdrawal ever made to that page. Nothing published there has been reweighted, reworded or withdrawn. The change was which page the record is kept on, not what the record says — which is why the old chart is archived in place rather than deleted, and why this page is served from the address the old one used, so that every link ever made to it still resolves. From at least 1 September until 2 September the reference above was plain text rather than a link, so this page asserted that the old chart was reachable while offering no way to reach it. It was repaired on 2 September, no figure was affected, and the outbound links on this page are now counted as well as read before it is republished.
Why the weekly chart was retired, restated for readers arriving from the archive. The old chart grouped predictions by the week they were written and maintained its own population, reconciled by hand against the daily ledger. Two faults followed. A single ungraded call held an entire week's bar blank, so weeks that were substantially complete showed as unresolved. And because the chart's ledger was rebuilt every week or so while the letter's was recomputed every day, the two drifted; by 24 August the gap had reached forty-two items, most of it grades nobody had read across. Neither fault was caused by call length — the seven-day discipline has held since 4 August and the schedule above shows it holding now. The fault was keeping two ledgers. This page keeps one.
Grouping by grading date rather than writing date is the change that fixes it. A prediction's grading date is published in the edition that grades it, so a block can be closed the moment its last member is scored. Grouping by the week a call was written cannot close until every call written that week has resolved, which is what produced the blank bars. The cost is that a block no longer maps to a week of coverage, and a second cost has become plain since: graded-date blocks arrive daily and most are too small to read, which is why days are consolidated once enough of them accumulate, and why the most recent board is always printed in full underneath.
Where the figures come from. The lifetime figure is quoted directly from the daily edition of 8 September. The block means are derived by differencing consecutive published ledger anchors — the editions of 27 July, 1 and 4 August, and 16, and 23 August onward, each of which printed a running mean and a count. Differencing rounded totals carries a tolerance, so block means are good to roughly a twentieth of a point; recomposing the eight blocks above returns 1362.46 across 267, a lifetime mean of 5.10, which is the figure the edition printed from its own running total. The two routes agree exactly for the first time on this page, which is a rounding coincidence rather than an improvement in method, and the edition's figure remains the one shown. Until 2 September this page carried one exception, where the edition's own figure was not the one shown; that exception has closed and every figure above is now the letter's, by the letter's stated method.
Form since the rebuild is computed from two published anchors and nothing else. The rebuild of 16 August printed 4.89 across 169 finalised predictions with 79 hits, and every edition since prints a running mean and a count. Differencing those two gives the figure on any day, with no recourse to anything unpublished and no dependence on an intermediate day. It grows rather than rolling, so a bad stretch stops being quietly discarded off the back of a window. The rolling fifty-prediction measure it replaced could only be read off this page while the fifty happened to sit on a block boundary, and once it stopped doing so it needed individual grades this page does not hold.
The recent record is above five for a tenth reading, and the hit rate since the rebuild is above even for a third. The 98 predictions finalised since the rebuild run at 5.46, on a tolerance of 5.44 to 5.48, against 5.05, 5.08, 5.09, 5.19, 5.21, 5.29, 5.36, 5.41 and 5.45 at the nine previous readings. The lower bound has risen across all ten — 5.01, 5.04, 5.07, 5.16, 5.18, 5.26, 5.34, 5.38, 5.43, now 5.44. Of those 98 predictions, 52 are hits, or 53.1 per cent against 49.1 lifetime. The same cautions belong beside it, and one more today. More than half the calls landing above the hit line is not the same as the mean clearing it, and 5.46 out of ten remains a modest number. The run of strong boards ended today at 5.50, and the rise in the mean this reading is one hundredth of a point. And a rising mean says nothing about whether the propositions being graded are worth grading, which is what the baseline above is for.
Six known ways this scoring system can mislead, restated here so a reader can discount for them. First, most panels are built from change-propositions priced low, and most days most things do not change — a correctly-priced non-event scores the same as a correctly-priced event, and the format supplies far more of the former. Second, some hits rest on non-observation: graded yes because no evidence of the event was found, rather than because evidence of its absence was found. Those are capped, and one hit on the most recent board sits on that footing. Third, a threshold occasionally gets set where routine events already clear it, which is a fault in specification rather than a success in forecasting. Fourth, and new, the system can also punish itself uninformatively: a proposition written in the direction the desk disbelieves, at a low standalone likelihood, can only lose, and its failure teaches a reader nothing. One such call was graded 2 out of 10 on 31 August. Propositions are now written in the direction the desk believes, and a positive proposition is not published below an even standalone. Fifth, and newest: acting on a correction can switch off the measurement that produced it. The panel has been built to the continuity finding since 1 September, and the board of 2 September was four continuity propositions and nothing else — so the split that finding rests on could not be observed at all that day. A desk that corrects itself into a single kind of proposition stops generating the evidence that would tell it when to stop. The remedy adopted for that — requiring every panel to carry at least one change proposition — proved impossible to satisfy honestly, because propositions must also be written in the direction the desk believes and must close within seven days, and most days most things do not change. An honestly priced change proposition inside a week is usually one the desk expects to lose, and the direction rule forbids publishing it. Six boards passed with the count unable to advance, which was a rule defeating a measurement rather than a run of bad luck. That rule is retired from today. The fault was in the measurement, not the panel: a board of four calls on one day is too small a container to hold both kinds of proposition without manufacturing one. The counter is now computed across a rolling window of forty finalised predictions instead, from a flag written on each prediction at publication, so the desk never has to invent a call to keep a statistic alive. The panel of 7 September carries two change propositions and two continuity propositions, and neither pair was chosen to satisfy a rule. Sixth, and now the largest: an outcome can be decided by how a prediction was written rather than by what happened. This began as a rounding problem on 4 September, when a threshold was lost by one tenth of one cent on a series published to three decimals. It has since appeared three more times in three more forms — a proposition surviving on one adjective, a heading and a specification describing different events, and a falsifier abbreviating its own object. Four consecutive boards turned on it, the fifth did not, and the sixth turned on it again in the desk's favour. A record that moves on sentence construction is measuring drafting alongside judgement, and a reader cannot separate the two from a score. The defences are narrow and are set out in full above.
