Because of the fiberglass tensile members in the
belts we use, there isn't much 'stretch' in the belt at all, regardless of loading. Basically, if you're putting enough load on the belt to stretch it, it's about to snap, and cause a complete failure. Belts do not stretch appreciably over time. Theoretically, the teeth of the belt will deflect under shock loading because the tensile members do not support the teeth themselves, but that doesn't really affect wear and tear, that just increases the likelihood of ratcheting when you're overloading the belt's hold on the pulley.
