If you're being that accurate, there is no way Nadal is 185cm and Isner has been upgraded from 206 to 208.
ATP heights are not accurate by the cm anyway, so 2cm between 4 players isn't much difference.
As for your other post, I think Nadal is 184cm and Djokovic must be between 186 and 187 because I'm not above 189cm and next to Federer he's never looked 188cm.
I agree with you about Gasquet, there's no way in hell he is over even 183cm. Carlos Moya was also smaller than his listed height of 6'3''.
Nadal can look 185 cm sometimes, although I tend to agree most of the time he looks about 184 cm. Federer Looks more 185,5 almost always,sometimes it looks he could claim 186 cm though. Djokovic is definitely not less than 187 cm otherwise he would look smaller than he does standing next to 189/190 cm andy murray. Djokovic looks anything from 187 to 187,5 cm nothing less than that.
Djokovic just have really bad posture.. when he is with good posture he is really noticeable taller than federer by a good 2 cms at least.
And gasquet? If he is 180 cm that would be too much for him? how tall is in real lleyton hewitt? 176-177 cm ? no way he is 180 cm, he looks quite short next to federer.
