The thinking behind the prize money allocation is as follows. If player 1 cashes, but not players 2, 3 or 4, then because they have so many individual points from the league, they will take by far and away the majority of the 20%prize money allocation, leaving little for their team mates. For that reason their prize is the seat and the opportunity to win 80% of whatever prize money they may win. It"s in their own hands.So when the 20% is allocated, the points scored by the top four players will be discarded and the prize money allocated in ratio to the remaining points scorers.
