That portion of your statement doesn't sanity check for me; seems like a stretch. I do this routinely, and the base
that moves, and only a slight distance. I seriously doubt you have to be so delicate to preclude adding tension. I think if you pulled tension, then released while trying to hold the string with your hand/fingers, and you're unable to prevent it from retracting, you wouldn't be able to add tension by doing something is simplistic as pushing the base toward the tensioner to prevent drawback.
