I once had a grievance filed against me because opponent claimed I was stalling in a timed match with a slight lead. Opponent came back to beat me the last match we played and thinks I was trying to prevent a repeat, but the fact is I often take longer breaks between points as matches go on due to fatigue.
He didn't have solid evidence (he said she said) and committee threw it out.
There are time limits on changeover breaks.
Yeah this is the problem with choosing to do timed matches if you have the option to not play timed matches.
Just the other day I was playing a timed match and we went up 5-3 with a minute left on the timer. My understanding is at 5-3 we win the set if the timer goes off but if it's 5-4 we play a second set tiebreak. Instead of delaying, I just went ahead and started the next game so we could try to win it outright. I can't imagine taking the win in that scenario on a rule technicality, although some in this thread are arguing that's the right thing to do.
The timed part just creates conflict. The entire second set my opponents who were losing never wanted to take a changeover. Hard to blame them because at the end of the day we all came there to play actual tennis. Not play the rule book.
