CR and pump gas question

Don't ya hate when a thread goes a page or 2 sideways with an argument finally dwindling to "more heat slows combustion"
Too much fuel slows combustion as well when there isn't enough air density.
If it is correct, what is wrong? (And note I say IF...) We've all accepted info that spark plug location and chamber size are factors in speeding/slowing the overall combustion time and thus are factors to tendencies to detonate, so why not the idea that there is maybe another factor in the mix? Too much fuel also cools the mixture, so that is not an apples-to-apples comparison to just changing temperature. But if that if the case, that does not conflict with the idea that excess heat slows the burn... there is nothing saying that there is not an optimum temp/mix for burn rate.

I agree that the tests of power production with AL vs iron have not concluding anything about detonation, but these articles just weren't looking for that. So they can't be used to say one way or another, and drawing a conclusion either way is erroneous, IMHO.
