This decouples also the stat bonus updates from the threshold which creates less dependencies for tuning of stat bonus parameters. Perhaps a further fine tuning of the now separated coefficients for constHist[0] and constHist[1] could give further gains.

SEE simplification
Simplified SEE formula by removing std::min. Should also be easier to tune.
