Not that I have seen, nor witnessed. As I said before, I saw him 3 times this past weekend, from a few feet away, and took hundreds of photos (high speed), and video (high speed). He is using the same take back as he always has.
Lastly, as I said before you are comparing a "soft practice hit", to a match play FH he rips for a winner.
The most telling sign in comparing the two vids you compared are his legs/feet. Notice in the practice video you provide, his feet don't leave the ground, and he has very little knee bend. Whereas, in the match play footage he has extreme knee bend and explodes completely into the ball, launching his feet off the ground.
Drakulie, I am more than aware that I'm comparing a "soft practice hit" with a match play forehand. However, like I said countless times before, he is using that same "soft practice hit" forehand takeback during his real matches.
I'm here to discuss the aspects of his forehand takeback, not his footwork. I don't wanna discuss his footwork right now. Besides, the fact that he was going for a blazing winner (with extreme knee bend and all -- like you mention) in that 2005 video doesn't change the fact that his forehand takeback used to look different back then. Nowadays, even when he goes for winners, he still uses the same darn "shortened" takeback that you can witness in the practice video.
I know that you saw Federer practice in Miami. Maybe in your eyes, it looked like the same forehand as always. That's fine. I mean, you're more than free to think what you want. It's a free country. I'm just here to make an observation of what I personally noticed and I don't think it's a minuscule thing that nobody else but I can notice it.
