Why this formula appears here
The success rate p says nothing at all about the second factor. Two agents can share an identical p of 0.99 while their conditional severity distributions, , differ by orders of magnitude — one agent’s failures cluster near the harmless end of C , the other’s failures put meaningful mass past . A leaderboard built entirely on p ranks these two agents identically. An operator who deploys the higher-severity one because its accuracy number looked the same has made a real decision without the information that decision required.

Why Average Success Rate Hides the Failures That Matter Most
