Can you show your math?
I believe that GR racket is the base racket that Roger uses, same for his JB racket.
If I am going to assume that these specs by ART ART are correct (they seem very plausible), then I must also assume that the GR is NOT the base racquet. At least not without weight removed from the handle first. If you take the GR racquet and add 8 grams centered at 5.5" from the butt to reach these specs, you end up with a very crappy racquet by pro standards. And it would also be way overpowered for a pro at the low tension that Roger uses.
But a 13-oz racquet with 31.2cm balance and 375 SW feels sweet, spinny and fluid at low tension. And it serves bombs with ease.
