Does anyone have empirical data on Federer that might help us ascertain whether the new racket has helped his game?
To be fair, we should toss out the disastrous 2013.
How about a comparison between 2012 and 2014?
Rather than looking merely at results in slams (2012 obviously was better in this regard but we'd have to adjust for his decline with age in 2014), can we determine if the following have changed:
1) First serve speed
2) First serve percentage
3) Second serve speed...
All in all, has the new racket been good for Federer?
