I think you're just picking the cases that support your point, here.
Look at Federer. He's hardly the most muscular guy out there, yet produces the 2nd most RPMs on tour. Don't you think it's more to do with technique, rather than strength?
I think the point about differences in men vs women's movement sounds plausible.
