Johnny doesn't use CTE, I don't even think he's more than vaguely aware of it, if at all. He also doesn't use or understand any techniques for english compensation (back hand, front hand, etc.), although once again he certainly knows how to compensate based on experience for his equipment.
It's interesting talking to some of these guys about aiming, systems, etc., very foreign to most. Johnny for instance learned when he was a teenager and got really good with just raw talent, practice, etc. I think most professional and high level players are the same way from my conversations with them.
That's not to say the systems aren't beneficial, and maybe the newer Youtube-based generation coming up will be more educated in the more technical aspects of the game and we will see it hit a new level!
