The point difference calculation seems to be incorrect.

For example in this tournament: https://bracketmaker.app/tournaments/6QPn/?utm_source=share&utm_medium=social&utm_campaign=share_tournament&utm_term=6QPn#leaderboard

The point difference for Alex P is reported to be +20 when in fact it should be +18.

Max theoretical points = 14*24 = 336

Alex P points = 177

Point difference 177 - (336 - 177) = 18
