Abuse the time or abuse the time + 10 seconds? It's shifting the goalposts to accomadate players, where it of course should be the other way round. Unless you think 35 secs between points is a better standard?
As to your second point, isn't the player obliged to serve their 2nd as soon as possible ( no ball boys running)?
This is weird. It seems like you want to fight with me.
No, I do not think that 35 seconds between points should be the standard.
But I have timed carefully for YEARS now. Have YOU done the same thing?
The umps have never started timing at the exact end of the last point.
I would assume that at present they CAN call out the score immediately, right after a DF or an ace. I haven't checked enough to to know exactly what they are all doing.
The perception of time passing is not the same when the last point is very long with an exceptional amount of running. I am not personally bothered at all when a point lasts 15, or 20 or 25 strokes, the crowd goes nuts in appreciation and the score is called out after things calm down.
I've seen Nadal AGAIN AND AGAIN AND AGAIN delay way more than 25 seconds AFTER things have calmed down, and also Djokovic and a few others.
So I think ON AVERAGE the pace will be quicker for the really slow players.
Your point about players gaming the clock, deliberately taking more time, is valid. We don't know yet how often this will happen. I suspect that Nadal will take every second for every point, JUST AS HE ALWAYS HAS IN THE PAST.
Now, I'm done. If you want to argue, argue with someone else.
