My reply to Chris stands: Mr. Bernath, although "exposed to this work," does not seem to have adopted it explicitly in the seminar classes he is teaching. Why is that?
You have a 40+ year SHIHAN who studies something else and you expect him to start teaching it at a seminar ?
Case in point, I went to an Aikido seminar in New Jersey.
The woman teaching the seminar was quite skilled at Aikido. I am not. My aikido stinks. I can't move like that, just not trained that way. I looked like a fool, stumbling over my feet.
Why would a Shihan alter what he was doing until he was an expert at the new movement ? ESPECIALLY AT A SEMINAR, IN PUBLIC???? Playing with a few of his own people, maybe.....
Sounds silly to me, but then again, what do I know.
