Yep. I've seen that one before. And . . . I've spent most of this year trying to get my clockwork more crisp, working on it every single time I fly. It's gotten better, but I still have an huge, enormous, unbelievable way to go to get somewhere close to his flying. He's way more crisp backwards than I am forwards, and I've been working on the backwards pivot turns too in addition to the clockwork. I think he throws in an axel halfway up the window near the end of the video, just because, you know, he was getting kind of bored with all the other stuff.
Still working on the powerball option to free up more flying time . . . . plus I need to move to the (inland) ocean to get those smooth breezes (with a very vented kite like a polo).
Hmm . . . maybe I will have to go flying again soon-ish (not this weekend though - anniversary).
