Started from the 75 rows of The Last Line and opened every source. 51 dated rows are on the two tracks, each linked to a page that contains its number; 67 undated rows from Scale AI and Artificial Analysis are in the table of outside runs; 13 rows are listed as not on the record line and 9 as dropped."

   "text": "Corrections to the starting data found at the sources. Grok 4's 44.4% with tools is Grok 4 Heavy, which runs several agents at once; the single model scored 38.6%. OpenAI published GPT-5 pro at 42.0% (Aug 2025) and GPT-5.2 Pro at 50.0% (Dec 2025) with tools; both were missing and both were records. Claude Opus 4.6 is 53.0%, corrected by Anthropic from 53.1%. Claude Fable 5.1 was first published at 65.0%, and at 60.9% without tools, which is the closed-book record. Qwen3.6-Plus is 50.6%, not 43.4%. Z.ai's GLM scores and Artificial Analysis's scores are on the text-only subset. Scale AI's rows carry no dates, so they left the timeline."

   "text": "Two changes to the method published with the build plan: 'a year ago' is 365 days, not 356, and when several scores are published on one day only the highest can be a record. With the corrected data the six-month backtest of the straight line no longer errs in one direction: it was too low three times and too high three times."
