OK, a question for non-believers:
I have my righting pole, it is attached with two lines below the hulls, one forward and one aft. But I also use a line over the hulls that I hold with my hands. Would that be average between the two cases? Should I tension more with the hands?

Regarding the analysis only at right angle, I say nothing changes in the analysis as long as you are still standing on your feet, lets say 10° towards one side or the other. At some point after you succeeded to raise the mast above the horizontal, you come to a point where you are hanging from the rope rather than standing on the lower hull. When that happen, yes, it's better than the rope is over the hulls, but that's way after the critical point. Success is not conditionned by that situation. Maybe it doesn't even help, actually. As soon as you passed the equilibrium you want it to go slow so that it doesn't go the other way.
