In a perfect world, the DC braking current should stop flowing as soon as the motor stops spinning. As a practical matter, the timer is usually set maybe a second longer than actual brake time to cover for variations in actual stop time.

Using DC braking on a bump-bump-bump type jog application is a poor choice for the reason you mention. Switch to snubber resistor braking (often called dynamic braking) and set motor speed to zero between bumps without stopping the motor. You will be amazed at the improvement in precision and predictability you get.
