Teacher: the rear straight to the body

The rear straight to the body, from my motion capture (Muay Thai 02, take_02, 29.25–30.70 s), aimed at two heights: the lower abs and the solar plexus. A one-technique teacher in the opponent_body environment: every press is the body straight, and the parent holds every other skill.

run	parent	what changed	outcome	machine-hours, cost
bodycross1	guard14-45.9M	the technique and its input	stopped at 42.5 M: it hit below the lower abs	0.61 h, $0.41
bodycross2	bodycross1 42.5 M	never below the lower abs (a floor line)	stopped at 30.3 M for the bag’s placement	0.51 h, $0.34
bodycross3	bodycross2 30.3 M	the bag’s face at the reference’s impact point	kept 95.0 M: 57/64, no low blows, no falls	2.07 h, $1.38
bodycross4	bodycross3	retrained on the original (slower) elbows, guard18 outside the punch	kept 118.0 M: 23/24, no low blows, no falls	2.57 h (3 boxes), $1.89

bodycross3 was trained on the faster elbows guard14 had. Distilled into a student on guard18’s original elbows, it missed: 2/16, 16–19 cm short at the low abs. So the teacher was retrained to match the student’s body (bodycross4), and that one went in with distill2.

The lesson: a teacher must be trained on the same body and the same actuators as the student it will teach.

Every run
