Steve RA...The "bolt forward" may have been a misnomer but it does move slightly and takes the presssure off the lugs as the gas comes in behind the gas rings holding the bolt stationary (linear) as the carrier is forced rearward and the bolt rotates free as the cam pin does its' work.

I only have one piston rifle so my experience is limited in that regard.

But I do prefer a normal gas system's lower recoil impulse and smaller profile on the barrel

Bolt failure is a hard thing to predict.

If you do some internet searching you might be able to come up with some numbers.

I like to think I have some extra life coming since I use the JP enhanced bolt.

I have seen a lot of chipped lugs on 308 ars w normal gas.
