Always interesting. Thank you. Will there be a video for the kaisetsu of it? I learned it and practising slightly different. Tate seishan dachi instead of zenkutsudachi at the beginning. Not three gedan barai but two, first and third, the second became a very fast whiplash used like charging of the last gedan barai. And not yamazuki, ura tsuki and upper arm in jodan kamae pretty close to the upper arm in the opening technique of pinan shodan (yes, always applicable like a reverse tate tsuki in nagashi taisabaki). I like the way you use your body for the jodan gyaku soto uke, both at the he beginning and at the end.
