They got 0 point for the slams and ATP1000 no matter what if they don't play for whatever reason. As for ATP500, if they are injured for more than 30 days (or show up for promotions even if you can't play), then they don't get penalized.
It must be me, but how's that a penalty?
If you don't play, you don't earn points imo, doesn't really matter if you're top 30 or not. Or am I being too logical here?
I thought they'd get an extra penalty for not playing those tournaments.
