Well, since I have never been to a seminar of his, nor visited his dojo, nor subjected myself to his displays of gi, I cannot. Perhaps @Buka can elaborate on that having actually been to one of Mr. Dillman's seminars. But in that it seems his apparent application of gi never seems to be shown outside his dojo or outside his own students, it would seem there is some obscuring of true results. If I am wrong I would love to hear it from someone trustworthy like @Buka. FWIW, I do believe in gi. But not quite the way Mr. Dillman displays it.
