The recommended fix for this issue, is the obvious large scale reduction of all sway values when using any gun from a deployed or prone position. movement should be limited to minimal, trace fluctuations only.
The motion should be such that sway becomes a non-factor for stabilized shots from deployed positions under any fatigue conditions up to a range of at least 400 meters. This can be determined by the general placement of the reticle over a man sized target at that distance, and verifying that the sway does not exceed the area of the intended mark within the gun sight's point of view
