There are pretty standard ways to teach tennis at this point. All the top coaches coach a similar system. I don't really see people trying to hit a top spin fh using a continental grip these days. Some things are self explanatory once you hit some tennis balls and see the results. The same goes I don't need the science to tell me to not use a kids racket to play as its too small. I just know it.
