Spawn delaying and avoidment is tricky and doesn't works everywhere.
3-1: starting with much better position, getting worse knife-cheetah vertical combination (11000th frame) so removed knife tosser. Same time as previous runs because of the spawn avoidment. edit: but worse next level positions
We need to somehow go through that knife-cheetah with previous method (empty, l, l : -1.5 -2.0 - 2.0 sacrfice instead of this 5*-2.0 (-5.5 < -10.0)).. subposes mostly or miraculous (spawn) delay somewhere.
