partial-training will set counts to guessed 0 instead of absolute 0, so we will use OPTIMIZE_SIZE_BALLANCED instead of MAX for things that was not executed. We will still use MAX for portions with optimize_size and code detected by safe heuristics, like code just before abort. Honza > > Thanks, > Martin
