Yikes back atchya!!!!
No, we don't want to redecorate the wall, just looking into the distance at the wall you happen to be facing, and direct the jump away from the way. It seems by telling them to do the jump away from the wall they do better. It's an easy sell when I show them that the proper jump angle has them nearly 1/3 of the way upside down at the end of their jump.
Yeah, I know they never hit the angle but who cares. I show them they can leave the floor at a 40 degree angle from vertical, with power, instead of what they think is correct, like jumping nearly straight up and trying to reach around with their hands, head, and ribs.
One way or the other, they always make it back to the floor.
