The point is not saving the stopwatch. It is costing two proposed methods before either exists.

Standard minute value built from motion elements
The linear TMU model is a simplification of the MTM-2 data card, which is a stepped table by distance class and case — it tracks the card well across the middle of the range and diverges at the extremes, so short precise motions and long reaches both deserve the real table. Case selection matters more than distance in any event: a GET requiring careful grasp is worth two or three times a simple one, and choosing cases correctly is what MTM-2 training is for. Manual and machine time are added here as though sequential; where the operator handles the next piece while the machine runs, the overlap must be deducted separately.
