The passage around this formula
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.

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
