I know I may present a simplistic point of view on this one, but it seems to me that whatever the method (LOP or ROP ) you end up with lower temperature than the EGT peak ....So I can't see a heat related factor playing in the scenario.
second point; if you are using LOP techniques, you have more air than fuel in your combustion chamber, and therefore a better "cushion effect" ?
I accept any comment about those techniques, but I would appreciate a scientific explanation of the reasons why we should avoid or recommend those methods.
