Your description about what to do is seems perfect. But your explanation seems kind of magical. The energy traveling or building up description doesn't seem scientific to me. It might be useful to think of it that way but I don't think it's actually what is happening. Energy is not really building up because of the tempo - nor is it traveling down or up to the club/racquet head). Let me posit a better explanation - IMHO. Okay starting with the golf swing. You have basically three sources of energy. The energy you add in on your downswing. They energy you get from what they call the stretch shortening cycle. (briefly when muscles are elongated in one direction they want to switch back immediately to a more neutral state). And then we have the potential kinetic energy that we have stored from raising the club up high behind you. If you change direction too fast from the backswing to the downswing you are fighting momentum so thus that will hurt your distance. If you pause too long at the top you lose your stretch shortening cycle energy. If you cut your backswing to 1/4 you would lose that potential stored energy and you shorten your 'runway" and lose lots of power. So your golf pro is right but its not about energy moving up the club or anything like that.. Now with regards to the serve. If you start in a dropped position or pause in the loop - you ruin your stretch shortening cycle. If don't let the loop go to the end you shroten your runway distance. So there is a lot in common there. But the energy thing seems weird. So it strikes me your description of what to do is entirely correct but your explanation as to the how and why (and that of the golf pro) is more magic then science. But that is just my opinion. Not a physics major so maybe someone can clear it up for me..
Weighted donut is a great tip! Never heard that before but I immediately got where you're going with it!
