If you're implying that Peter didn't think much of Dan...then I suppose that it's best to talk to Peter directly about that. My impression however, based on conversations directly with Peter (not some ni-dan who sees him at seminars) is quite diferent.
I'm not implying anything of the kind. I'm simply reporting that Mr. Bernath, although "exposed to this work," does not seem to have adopted it explicitly in the seminar classes he is teaching. Because you know Mr. Bernath (I do not), you might ask him why that is.
