Ok, Does Nadal ever go beyond zero on the shot clock without warning?

[zuluzazu]

I do not watch all his match point by point so I may have missed something but I have rarely seen Nadal not ready to toss the ball and the shot clock has come to 0. In the rare cases shot clock goes to 0 I have seen umpires give him warnings. He uses the full 25 secs on the shot clock but is it against the rules to use the whole 25 secs? Also is there any rule regarding the time taken between 1st and 2nd second serves. I dont know of any rule but can anyone clarify it.

Also people shouting at the stats that Nadal was taking 35 secs between points need to know that that stat is calculated from the exact time the previous point ends but starting the shot clock is under the umpire's discretion and according to the rule the server must be ready to serve when the shot clock hits zero
