In times of COVID-19, I've seen quite some discussion about what the "R" in CFR stands for. Whatever it stands for, that's the right answer :-) Case fatality ratio - but not restricted to any interval Case fatality rate - but doesn't have a time or derivative (rate of change) component, which rates usually have Case fatality risk - akin to probability, definitely between 0 and 1. That would be my choice. It's shorter than the word "probability", and somewhat less frequently used, so it could be adopted for this purpose. Edit to add: Though "accuracyRisk" does seem weird. Better than "accuracyUnitInterval" though maybe.
