You picked 5 on at least 2 different surfaces because that leaves out Nadal and leaves in Fed, simply as that. And that's fine by me.
Likewise, we could use "at least 2 on each surface" to leave out Fed and leave in Nadal. Also fine by me.
I understand your point.
By the way, the second seems more relevant to me, objectively.
Why 5 grand slams on 2 surfaces would be more relevant than 2 slams on 3 surfaces anyway ?
