In a manually controllable device of the type wherein the position of an element proceeds at a rate in response to a first operator signal and the operation is terminated in response to a subsequent second operator signal, the improvement for providing an operator reaction compensated end point comprising: means for establishing a signal responsive to said rate; means for establishing a signal indicative of operator reaction time; means for producing an end point compensation adjustment signal based on the product of said operator reaction time signal and said rate signal; and means for establishing an end point position by applying said end point compensation adjustment signal negatively to the end point at the time of said second operator signal.
