it could be by design...I am so confused. IF there is indeed a division over 48 minutes then this quantity has units of performance over time. It is, like, wrong to divide the total performance "output" by 48 minutes, instead of dividing by the total game duration. It is really baffling that over 15+ years the consensus among the game maintainers for the main team stats appears to be "yeah this calculation is wrong, trivial to fix, but I like big numbers".
