In the history of sports and in our ‘winning is everything’ culture, I’m not aware of anyone who ever won every game, or every event, or every championship they competed for. Roger Federer, the great tennis player who some call the greatest of all time, has won a record seventeen Grand Slam titles. Yet, he has competed in more than sixty Grand Slam events. Thus, perhaps the greatest tennis player ever failed more than two-thirds of the time. While we don’t think of him as a failure, but rather as a champion, the plain fact is, he failed much more than he succeeded on this measure, and that’s generally the way things are for anyone. Failure precedes success. Simply accept that failure is part of the process and get on with it."

I assume it refers to 'the greatest tennis player ever failed more than two-thirds of the time' but what does 'measure' mean? Does it mean 'a measured quantity'?
