It will suit a specific type of player - the player that already scores well. The points awarding system hasn't changed. The only difference is that if they're only playing 75% of the game, then the scores at 75% are extrapolated out to 100%.
It rewards players who are doing well, pure and simple.
Just imagine seeing the table of players' SC scores at 3 quarter time, and then adding a third (put in the most simple terms, scaling notwithstanding).
