it's a double edged sword. Rafa and Nole do play grueling points so extra time may be needed in their matches, but he doesn't need 30 seconds in other rounds. So you have to enforce it by perception and the matchup.
WTF, may be needed? Based on what?
New ATP rule:
Rafa gets 90 seconds between points because he's so intense he runs everything, what a Spartan, he plays so many grueling points he deserves more time. It's unfair, but he is so clutch.
What the hell is that?
