there is such a thing in the industry know as FS...which is factor of safety
these things are over-designed
anything that involves humans which might pose a safety issue to them if it fails usually has a safety factor of minimum 2.5
that means that if the belt is meant to be changed at 100k,...it is designed to last until 250k...
this is so to take into account any unforeseen occurrences that might degrade the belt during its normal operation
so even if it halves the life of the belt,...it will still last to its scheduled change at 100k
