4) That thing where each arm and leg is attached to a different horse and they gallop in different directions
Drawn and quartered.
Even though there is a horse tied to each arm and leg, one of them (presumably one of the legs) would remain attached to the torso.
I can see that timing it and training the horses to gallop away at full speed, such that the torso is left cleanly in the center of the towne square, is probably a lost art.
"Dude, 3 inches from ground zero. That's awesome!"
It occurs to me there would be two measurements -- deviation of a standard center point (center of gravity, perhaps near the navel) from the at rest point, and rotation of the torso in degrees. Actually, there'd be the roll angular displacement of the torso, too, as well as a "tidiness" factor for folding of the torso.
3" deviation
17 Degree rotation clockwise
Video shows a 274 Degree roll rotation "Oooh, Bill, that's not gonna please the judges. Tsk."
And a midpoint flop, but it straigtened out before landing.
9.5 8.7 6.6 9.8, for a total of 34.6, putting him solidly in 17th place. Oh, Bode.
