Alright guys. Heres something else I found rather interesting and useful charting a Ladder Test on a large sheet the way I illustrated above.
I graphed the POIs in the paint program with a blue line and you can see the barrel vibration on the paper from shot to shot. kinda like an ocilloscope still. or waves on the ocean. and notice how straight the curve is from shots 14-18 and then how it goes right back into a sharp whip at 19 and 20.. A recoil vibration pattern graphed on paper. How fascinating is that..
Im liking this alot.
