Never really got into TMs stuff. I have had conversations with other TM followers; RHC, RayR, etc. and they have explained some things to me. I have also had some direct conversations with TM while at BaseballDebate. I know others have had negative dealings with TM, but he was always polite with me and answered my questions without diverting (as some do here). That said, there are aspects of his teaching that I simply cannot reconcile. It's my understanding that he continues to evolve, and I honestly have not kept up with it.
Ultimately the most important thing is the success of the players. Your DD has a great swing and I wish her all the success in the world. @Work=wins 's daughter has a very good swing as well and I wish her an equal amount of success. It's interesting that they have followed very different paths, but the success is what's important.
To be clear, I strongly dislike TM's venomous online persona. I agree with the mechanics, but not the personality. Having my DD work with @Mike-Coach Q gives her the mechanics we agree with, delivered by a kind and skilled instructor. Personally, I think TM's HLP is being instructed better by the "next generation" (guys like Mike) than by TM himself. Teaching effectively is about being able to communicate ideas in ways people can relate to, not just the material.
