7 emulators 655 tests

Results as of this run. The arrow shows each target's movement since the previous run it was tested in. The suite grew this run, so an upward arrow can be the new tests biting rather than a target getting worse.

When this run was published the board led with a single correctness percentage. The figures here are that run's own results restated as divergence and coverage, so they read differently from what this page showed at the time. The changelog has the change.

Suite grew from 625 to 655 tests this run.

That's 30 new tests measured against every target. Movement below compares to the previous run, so a rise here is as likely to be the stricter suite as a real regression.
