I'm a new poster fan on this forum.
Well, this classement is no ridiculous at all. Gonzales n°1 is a probability, even if I class still Rod Laver over everybody. Here is my top 10 on a period 1948-2012 (I won't try to analyse before 1948, whereas amators and pros could compare each other. How hard is to admit Lacoste, Cochet, Vines and Tilden were above all these guys (or not) !
1 Laver 2 Federer 3 Rosewall 4 Lendl 5 Gonzales

I think my different ranks from the original one come from my sensibility to consider not only slams but other tournaments like master cup or masters 1000, where the top champions were present. Lendl was amazingly regular between 1982 and 1987 in these other tournaments.
I agree with you on several points, but if you highly consider players' regularity outside of slams, I'm surprised that you put Borg so low, as his percentage of losses was very low, even though the tournaments outside slams were even less representative (that is not with all the top-players) in his time than in Lendl's time ... but he played a little bit less of them than Lendl. Also even though Borg had a surprisingly high number of walkovers.
Borg's winning % : 84% in 1976, 91% in 1977, 89% in 1978, 92% in 1979, 90% in 1980, 85% in 1981.
Lendl : 92% in 1982, 82% in 1983, 79% in 1984, 92% in 1985, 93% in 1986, 91% in 1987, 84% in 1988, 92% in 1989, 82% in 1990
