In my experience waxing also makes the game considerably faster.
I put two coats of carnauba wax on my TZ and it changed it dramatically. Suddenly the ball traveled what seemed to be at least 25% faster. Some shots and post rebounds are like bullets. I can't get close to my previous high scores (which weren't great to begin with to be honest)
Worth doing for the protection and longevity aspect, but it does also change the dynamics from what you might be used to.
