The problemOverview

An EA FC card is a list of two-digit numbers. What a player feels like under your thumb is something else: the numbers after chemistry has been applied, after PlayStyles have moved the curves, and after the game’s own non-linear scaling has decided that the gap between 84 and 88 is not the same size as the gap between 88 and 92.

This calculator models that second thing. It exists because I wanted the version of it I could not find.
