Bingo. There is also no (easy) way of knowing which way the degradation is going to go. About the only way of knowing is to strap a head form with an accelerometer into the helmet and drop it on an anvil. But then the helmet needs replaced and the test equipment is a wee bit more expensive then a new helmet
