This is a recommendation I've seen before, and it seems reasonable to me.... however, we have something on the order of 1000 cycles on our practice robot catapult with no noticeable wear or potential failure of the cylinders, and we are using the cylinders with no hard stop. Mind that we avoid dry-firing like the plague, and under normal launching conditions the cylinders aren't hitting their end of travel with such an absurd velocity.
