Concurrent with the decrease in bot

Concurrent with the decrease in both alpha and beta moments, there is
an increase in the moment-to-force ratio of the retraction spring,
resulting from the lower applied force produced by tooth movement.
Since the M/F ratio increases as the spring deviates, the spring should not
be reactivated too often. Frequent reactivation will not allow the spring
to achieve a high enough M/F ratio to produce translation.
