AC-
I do believe you are correct... two laps around the dial or thereabouts. As I read it, he's doing either about 200 or a bit over 460. Since the wings appear to be over at about 60 degrees and the thing's not falling out of the sky with minimal sideslip, my money's on 200.
G's should be at 2 if it's a steady turn, but perhaps he's somewhere in the middle of a wingover or some such. Either way, looks like good fun!
