What are the real swingweights of the pros

[realplayer]

Safin's old Dunlop PJed racquet's specs (unstrung):
Grip Size: 4
Weight: 330g
Swingweight: 296
Balance: 30.7cm
Stiffness: 66


So safin played with a racket strung of around 350 grams and a sw of only 326!!!!



Safin's most current setup (unstrung):
Weight: 336g
Swingweight: 335
Balance: 31.2cm

What a difference!!!! I always thought they changed only minor details. Can anyone explain this!!

I've read some threads over how pros set up their rackets but the most important information is not there. The actual swingweights. Is this a big secret or something!!! There are some pros stringers on this message who should know. Lots of people on this board would like to know i'm sure.

This should help. It's a list of estimated pro swingweights based on the measured weight and balance of 81 pros as of the 2005 French Open.
