Yes it did., But based on the movements, it appears its intentioned manipulated movements.
That Vid is Worthless for whats being argued here. It clearly shows a intentional movement of the rotor to show the point of proper phasing. You cant tie in its movements to a mechanical advancement. No way, no how. IMO, anyways.
EDIT; I also know what Trendz video is going to show when he plays it. { A Stationary Rotor to its terminal.} And no I haven't seen it, haven't been told the results of it, don't even know if its been made yet. But, I know.
