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.

A record appears here because it carries arithmetic in its own frontmatter. If a record you expected is missing, it was filed under a different subject — the full list is on the topics index.
