I may have not have explained it like this, but this is the reason why I do 91-93 octane, Not because it’s “premium”. I hate it that it is expensive, partly due to the fact that people use it even if they really don’t need it.The part of higher compression detonation that causes damage is the combining flame fronts. The energy pushing piston to push down the other way is not what causes the problem.
This is why a lower compression engine can knock(ping) its whole life and a higher compression engine will start to eat itself up over a shorter amount of time.
A higher compression engine can have multiple flame fronts of detonation inside the cylinder. These flame fronts can combine into a point to create serious damage inside the the cylinder. It’s the multiplying effect that causes problem.
I rather have those small pings to a minimum. At the same time, knock sensors won’t have to pull the timing and prevent the injectors from spraying more fuel than necessary, keeping the engine running in it’s most efficient combustion cycle operation.
