I agree that he is conserving energy.
I've yet to see anything other than opinions offered as proof of such.
Would love to take a look at any facts folks might have to offer up as a basis for their opinions.
Correct me if I'm wrong Shanks- you're saying he's slower when he's overbooked. Consequently he's cut back on his schedule and now is just as fast as ever. Is that right?
yes, almost as fast as ever in slams.......i have noticed particularly last year that he is not caring for anything but slams and is just unloading in slams.......i think that approach is mainly responsible for his top movement in slams even at 30.......it's not that he's cutting back much on his schedule, but you can see he doesn't waste many reserves for unnecessary tournaments.......
As to actual speed of foot, we'll have to await a more accurate measurement than just our observations.
Why wait, you have the internet to try and disprove it.
I'm not so worried about court speed, it's the other areas like the forehand being not as reliable,
the serve taking short vacations and whole match intensity.
He looked pretty good against Nadal, but goes off of what's working at times IMO.
Fed's already done enough, the others can stand in line and try to match some of those records.
I agree with some that he saves himself for the slams, trying in every tournament seems to be too much.
