Murray is like the very opposite of a vulture.
On topic: com. players 'have' to have 4 500s(+MC) tournaments per year. For every one of the 4 they don't play, they get a year long 0-pointer which can not be replaced. They don't need to count the points, just play the tournament. Assume that Murray plays only Tokyo until the end of the year, that's 2 500s for this year, 4-2=2. He'll get 2 0-pointers. Players have 6 spots for non-mandatory tournaments, 6-2=4. He'll have 4 places left to count his 4 best results (point wise), not counting mandatory tournaments.
