I've been back and forth on this trade all season and here is what I can and cannot do reliably:
1. Backing out of a shooting position and taking the last 1-2 paper targets works well on a slow, retreating move - mostly A hits, a few C, very few misses. Gun is fully presented, knees are bent, hips low, back fairly straight, stepping backwards slowly, using drop steps for side to side moves rather than twisting the hips, shoulders stay square to the target. This is actually quite stable and I use it as much as possible to cut down transition time between positions.
2. Firing while decelerating into a new position, essentially the inverse of #1 also works, but is less reliable and gives more Cs and a few misses. I usually take make up shots and as I get better at it hopefully I'll need less make ups.
3. Firing while accelerating toward a target or anywhere near top speed between positions is a total bust for me - almost all misses and if I'm luck a few D hits.
So I'll shoot for the few steps out of a position and the last few steps into a new position, I'll avoid shooting anywhere near top speed between positions, and this approach is definitely working for me.
Lastly, I'll add that I like to enter and leave on paper, shooting steel in between paper. That way I'm still there if the steel doesn't fall.
