With regards to the teacher of the staff? I asked if you knew of such a person for I got the impression many folks seemed to think O'Sensei never had a precise way written down.
Maybe I'm wrong there.( excuse the off topic aside)
If O Sensei had definitions or transcriptions for his staffwork I'm sure we would have seen them by now. It's a time consuming process which I used to do a lot of before. I compiled a dictionary of transcribed staff forms couple years ago but that was when my work was still external. I haven't done so for Internal yet because I don't think it's necessary. I've also learned that many of the complex dynamic forms don't like being defined to one series of locations, they like having a range making the transcription process even more tedious.
