If you clamp a muzzle then no amount of stabiliser or brake will make any difference. The barrel and pellet determine that.
Follow through however will aid a better shooting process. Scatts can't predict shot placement and they aren't a scoring system, they can only show relative movement. It will show where the rifle pointed when the shot was taken and in the duration it takes to get to 10m (or whatever range you are shooting at) how far the barrel has moved. But that's after the shot has gone. There's not enough air in front of a pellet to stabilise the barrel before the pellet leaves.
