An advanced correction results in some degree of advanced anticipatory spacecraft corrective movement which is not good. A rather better idea is to have "rate of change" output, as well as the "direction of change" output, from the stable platform system. This information is used to vary the force of the corrective motion in real time, concurrent with, and equal to, the disruptive force.
