Usage Data
What courts write, counted: each number with its sample, its basis and its date.
When a chapter calls a form a convention, the counts behind it are here: what our samples of opinions contain, the reporters they cite most, how they write the abbreviations, how often two reporters sit side by side, and how often each signal appears. Each count gives what was counted, out of how many, and when. Every figure comes from a saved run and was checked against its saved files on Oct. 13, 2026; no parser has been rerun since. A count is usage, never a rule: it does not tell you what a court asks of your filing or whether you may cite a source there (14.11; 14.10), and no count here sorts the opinions cited into published and unpublished. Labels: CONVENTION for usage counts, HOUSE for our own choices, UNRESOLVED where the data cannot settle the question.
