The numbers are based on the ATP site. It doesn’t imply that I view this category as more fundamental than others, and I still think that Sampras is in the top 3 (or perhaps top 2) in the open era, in spite of the fact that his numbers in these departments would not match up well with these players. For some reason, the 90s did not produce great numbers in this department. Whereas Connors, Borg, McEnroe and Lendl were at home with cumulative percentages in the mid-80s for much of their careers, once they retired we had to wait until Federer for anyone to even break 80 at any point. Connors record in particular is very striking. On 9 different years, he ended the year with a higher career percentage than anyone in the open era has ever attained at any point in their careers. Whereas no player from the 1990's ever reached the 80% mark in career percentage at any point, Connors spent 23 years with a career percentage above 80. If he had retired at the age of 38, he would have retired with a higher total career percentage than Borg.

I may do some revisions later based on DC records that seem to be missing from the ATP in the 1970s, which would affect mostly Borg. When introduced, it appears that Borg’s 608-127 final record will go up to 638-130, and so his final percentage would change from 82.72 to 83.07. McEnroe would go from 875-198 to 883-198, and his percentage would move from 81.55 to 81.68. This would imply no change in their standing in this category, but it would have a slight effect on the peak career percentages in some years.

After the data, I thought of some possible ways in which it may be viewed and classified. Anyone can sit down and invent ways to play with it.
