oh and I am assuming you calculated the RG 2008 final stat for nadal from the official website ? well those stats are totally wrong ...I don't know what the hell the statistician was doing !
I did the stats for the first set:
federer: 3 winners, 17 UEs, 7 forced errors
nadal : 6 winners, 4 UEs, 8 forced errors
they have :
federer : 9 winners, 12 UEs, 3 forced errors
nadal: 15 winners, 3 UEs , 3 forced errors
while you could say UEs are subjective, the winner counts are way off
federer won 52 points in that match, they have him @ 31 winners, nadal at 7 UEs, therefore federer only forced 14 errors from nadal ?
he had 31 winners , but forced only 14 errors from nadal?
