Some of these numbers are completely outdated,Davydenko uses his rackets with 40Lbs,and the top 5 strings lower a pound as they go up.
But expected most pros using tensions in mid 50's and low 60's as they can generate a lot of power themselves with a lot of control.
I wouldn't take that website very seriously at all. Some of the strings and tensions are correct but there are a lot of specs that are blatant errors.
Things such as Federer stringing at 55/52 lbs. with the BLX, when it is pretty common knowledge that he has been stringing around 21/19.5 kg or around 46 lbs on the mains lately.
Also, in the case of Tommy Haas, he isn't even using Alu Power. He switched a while ago from Full Natural Gut, to Natural Gut/Big Banger Ace. His tension in the lower 60's if I remember correctly.
