He's most #6, based on what analysis I've read, because of his high first serve percentage in.
I've read an analysis of his serve, and its mostly his explosive leg strength and shoulder flexibility that have gotten him that far.

I think I can do that, and I asked my science teacher-pretty athletic guy, and he could do that too..
I'm not really sure what they mean by that.
