It's a classic problem and one that all teachers fall in to: doing one thing and explaining something else - and (most of the time!) without meaning to. I try to listen to explanations as well as watch and feel, but pretty much always give precedence to what I see and feel!
Excuse me, but this set off my bull meter. Really? All (even "most") teachers can't explain what they do?
I've known teachers who don't. But those who are good, and try, but can't?
Never met one.
(Edit: Well, there is the discussion of Ikeda Sensei upthread. But he's explaining what he's doing with the vocabulary he has available. He's not doing one thing and saying another.)
