Great video UTC
I particularly like your first 360. Technique looks spot on. Mast pushed towards the inside of the turn, front arm straight then rig swung right back so the foot of the sail is touching your legs.
Your analysis of board angles is interesting but a little misleading. Ian K nailed it by saying my turn was pulling some g's. I was cranking some of those 360's but you don't need to to make a successful one.
If you compare it to a gybe, a gybe can either have a long arc or a tight arc. The tighter the arc the more commitment required the higher the g's
I picked up the Phantasm 926 and gave it a run yesterday.

This foil has incredible glyde making it a 360 machine. It just floats around
Ill see if I can post some footage of a longer arc, more upright 360.
Look forward to you getting back on the water UTC and translating your landsailing skills to the foil
