Hmm.... I don't have all eight of Rafa's RG finals.... will have to search for them... mind you, I "only" have ... oh, about 175 of his matches.... will look around...
Same with Roger.... I think I'm missing two Wimbly finals ... among the 230-240 or so RF matches I have (I haven't categorized every match, it's an ongoing project, so I never have the exact amount....) [and personally it would be very nice to "up that a notch" to eight final wins later this year!!]
But yes ... sounds like a plan ... maybe one of the "extra" topics you created can go to NADAL Matches, with all RG finals as a subject, and a second one to "FEDERER Matches", with all Wimbly finals as a subject.
And then, of course, my challenge will be to fill in as many other matches as possible. Hmm.. big project...
