I could see a potential rule change coming for toilet break. They didn't have time monitoring between points before and it was abused, now same thing is happening again. I am pretty sure some restrictions will come following the recent events. Even 5 minutes is already disrupting the moment. I remember seeing players before changing quite fast and rushing back to the court. I assume they were doing this also due to respect for the opponent.
I think that now that the focus is on it, the rule will be changed/clarified. It's better for fans and for TV. Tsitsipas, in his very defensive presser about it, cited Murray going off court before the 5th in the USO final v. Djokovic in 2012. (NB: Djokovic also went off court after losing one of them, in that match.) But Tsitsipas was told that Murray only went off for 3 minutes. I remember clearly reading that Murray said he went off to have a chat with himself, off-court. At the time, I worried if it was gaming. But, 3 minutes, I think you get them. Whether it's to change your kit, have a pee, or talk to yourself in the mirror, I think 5 minutes should be maximum. #rulechangenow
