@fatdog, that is really interesting to me. It sure seems like *nothing* is preferable to “bad” reps (or, at least, contradictory reps). I think that was the saving grace in my case; I put the wheelies away for a decade and a half, and then brought them out, so all my brain had to do was send a synaptic elf into the vault to retrieve old files.
I find that the people in my beginning music classes generally perform better learning the skills than the folks who have some experience on the instrument, because there is no bad habit and bullshit to erase with the absolute tabula rasa folks.
