Method

base: reference class = the meeting right after the first hike of a cycle (2004: hike, 2015: no, 2022: hike, 1999: no); about half; 45%. signals: LR 0.6 Governor Waller (8 Oct) left the door open to a pause; LR 0.6 weak September payrolls (+29k, unemployment 4.2%); LR 1.2 core PCE 3%, energy shock. Honesty note: a search snippet summarising market pricing was visible before I wrote this number, so this question's errata-vs-crowd comparison is contaminated.
