You're apparently not even trying to understand what you're actually responding to, which makes any exchange of opinion quite meaningless. No offense.
I understand what you are trying to say. But you're not getting what I'm saying.
What you said is not applicable in the case of this video as comparision is b/w 12/14 and 17 federer at the AO.
I doubt you'd find even a few people saying fed's BH in 12 or 14 was better than in 17.
The video is valid , it shows the difference in BH speed and technique with the new racquet.
But no one is going on actually denying that evidence here.
and yes, Nadal's FH and movement decline is also a factor. He doesn't suck, but they have declined. Its not the only factor, but a factor nonetheless.
To get the 'proof' for that ,
forehand :
a) you need to get the stats for : no of winners hit from the FH, no of errors forced by the FH and no of unforced errors from the FH.
for matches across all seasons.
Yeah, good luck with that.
Many a times, the eye test does show things correctly.
For instance,me and NN over here caught Federer's improvement on the FH right away (compared to 2014-16) :
(Nishikori match at the AO):
Federer's forehand, though.
true ....can't remember the last time it was this good ....some time in 2012 ?
Pretty sure that's the best it's been with his current stick, and yeah I'd say since 2012. He had supreme control on the forehand for a lot of 2012, but he perhaps took it early better here. If we compared this performance to his best 2012 performances, we might be saying he did better today so maybe we could go even further back .. but at least 2012. He is way way weaker on defence on the BH side though. He did make many truly superb forehands on the run and the on the stretch tonight. Also, his timing on the forehand return off slower serves was really good and he was very aggressive with it, which isn't so typical for Fed. Sometimes he adjusted his timing slightly mid swing and still smacked a winner.. like he was waiting on the ball longer.
yeah, the best it has been with the current stick...
I might putsome of performances of 2012 FH on par/a bit over this, but would have to revisit tbh ...
-----------
Now, if you have some concrete evidence to show otherwise, I'll check/listen.
But there isn't any concrete evidence to show that Federer's FH in 17 is up there with his FH from 2004-07 or his movement or his returning (well , actually return stats clearly show his return was better in 04-07).
serve is a tad better, tactics better to some extent and topspin BH is better. But that's not enough to compensate for the other things mentioned above.
I'll go with the eye test/observations, until then.
