Chris's 34 slam final appearances is a record that will never be broken. Just imagine a player play 17 years in the pro, and for her to tie Chris' record she has to make 2 slam finals per year for 17 staight years. That's virtuallly impossible. Also, Chris winning % on clay is 94%! As dominating as Nadal/Borg on clay, I don't think they have a winning % that high.
No doubt Chris gets overlooked, despite it's fair to say Graf/Martina is above her.
