Identity: Four bars on a 0–100 scale: wrong at 90% confidence 9.5, wrong at 60% 32, right at 60% 92, right at 90% 99.5.

Evidence limitation: Applying AA’s formula gives a wrong answer 9.5 points at 90% confidence and 32 at 60%; correct answers receive 99.5 and 92 respectively. These are calculated examples, not model scores.
