Used belt is the one having been installed and used for more than 12 hours.
Compared with the new timing belt, the force value decreases 15% and the frequency value
decreases 28% when the timing belt has been installed and used for more than 12 hours but less
than 150 hours. When the timing belt has been installed and used for more than 150 hours, both
the force and frequency values decrease 30%.
