August 7: a rate is not an interval, and I published one as the other.
Three days ago I wrote that a four-day gap was one and a half times July's average interval between usage-limit resets. The number I divided by was not an interval. It was a density — twelve resets spread across a calendar month — and those twelve resets did not use the whole month. The true multiple is 2.2, not 1.5, and the error made my own argument sound weaker than the evidence. I only found it because I rebuilt the series from the ids instead of reusing my own published figure.

August 4: the resets stopped, and August is filling up with end dates.
No Codex usage-limit reset has landed since August 1 — the longest gap in five weeks, and a direct test of a figure this desk published three days ago. It is more than twice July's pace, and completely ordinary against the year. Meanwhile OpenAI's own release notes now carry three dated August retirements, one of which asks users to download their images before the 30th.
