Total lock is the sum of drop and run to the banking. It must be equal on the entry stone and exit stone. The deign of the escapement determines how deep total lock should be. As a general rule, it should be equal to approximately 1/3 the length of the impulse face of the jewel for slow-beat watches, and approximately 1/6 of the length of the impulse face for high-beat watches.
If drop and total lock are equal for the entry and exit stones, so will be the run to the banking.
