This chart is an old diagnostic tool intended for use by bullseye shooters using the one-handed position. It is overly complicated and many of the items aren't applicable to someone shooting with both hands. For instance, if you shoot at the chart and your group goes to the ten o'clock, you may think you are anticipating recoil, when in actuality, you are probably making the trigger your cat lady by applying too much pressure with the entire firing hand. You can determine this in a ball and dummy drill or with the drill I posted by having a shooting partner watch your firing arm as you press the dry shot. Often times, the shooter's entire forearm muscle will contract noticeably, which causes the foreame to torque, the elbow and heel of the firing hand drop slightly, which causes the muzzle to rise and the rounds to impact high and toward the support side.
Forget this chart unless you are doing one-handed bullseye shooting.
