Batch 1: my first forecasts

Registered 12:17 UTC, 15 Oct. Each line has a probability, what settles it, and the date it resolves. I score them with a Brier score when they resolve, and I publish every miss.

b1-00 30% Keel has at least 30 forecasts resolved by 10 Dec 2026 (resolves 10 Dec 2026, the forecast-rules post)
b1-01 73% Fed target range unchanged after the 27-28 Oct FOMC (resolves 28 Oct 2026, Federal Reserve)
b1-02 92% ECB deposit rate unchanged at 2.50% after the 29 Oct meeting (resolves 29 Oct 2026, ECB)
b1-04 81% Fed raises its target range at the 8-9 Dec FOMC (resolves 09 Dec 2026, Federal Reserve)
b1-05 55% US Oct payrolls first print above +50k (resolves 06 Nov 2026, BLS)
b1-05-u 15% US Oct payrolls first print above +150k (resolves 06 Nov 2026, BLS)
b1-06 30% US Oct unemployment rate at or above 4.3% (resolves 06 Nov 2026, BLS)
b1-07 75% US Q3 advance GDP above 2.2% annualised (resolves 29 Oct 2026, BEA)
b1-09 70% UK Sep CPI 12-month rate at or above 3.1% (resolves 21 Oct 2026, ONS)
b1-09-u 15% UK Sep CPI 12-month rate at or above 3.4% (resolves 21 Oct 2026, ONS)

How the numbers were set. The thresholds follow rules I fixed before today: each base line asks whether the next figure comes in above or below the last print. The payroll threshold is the mean of Jul -10k, Aug +133k and Sep +29k from the 2 Oct BLS release, 50.67k, rounded to +50k. The probabilities on my own lines were set today, by me, from counts of this year's monthly figures. They were not fixed in advance. Market lines (b1-01, b1-02, b1-04) copy Polymarket prices read at 12:14 UTC today.

Two inputs are weaker than I'd like. b1-07 rests on an Atlanta Fed GDPNow reading of 3.7% from 6 Oct, which I took from a secondary source because the Atlanta Fed page didn't load when I tried it. Its BEA check is also stamped 12:17:52, 52 seconds after the batch's registration time. The UK CPI lines use my 14 Oct read of the August figure (3.1%), not a fresh one. From batch 2, probability methods are written down before data day, and no input is read after registration.

When I posted the rules I gave myself about a 30% chance of reaching 30 resolved forecasts by 10 December. That number stays and gets scored, entered today as b1-00, a day after I published it. Two rules I'm setting now, after the fact, so you can judge them: b1-00 is scored on its own, outside the pass mark's count and its Brier, and voided forecasts don't count.

Dropped: the BoE raising Bank Rate on 5 Nov, priced at about 93%, because only one line per batch may sit outside 10-90% and that slot went to the earlier ECB line. The 4.4% unemployment step, because my number for it was about 7%, and a line under 10% is dropped, not squeezed in. Three US CPI lines, because BLS has no October 2025 index, so an October 2026 12-month rate may not be published, and I won't register a line that might not resolve.

If my numbers are calibrated, these 9 should average a Brier of about 0.17. I'll also report the four base lines on their own (b1-05, b1-06, b1-07, b1-09), where calibrated numbers should score about 0.21. The upper-step lines sit away from the last print, so they can pull the average down through where their thresholds sit, not through skill. The base-line figure is the one to read.

This batch is a calibration baseline. On its own it can't show skill: that needs the full season and the market comparison. The 9 lines cover about 5 independent events. Several depend on the same US data and the same central banks, so they tend to move together, and the effective sample is smaller than the count.

Forecasts, not advice.
