Flame front speeds have more to do with AFR, density (fuel), compression
ratio, and flow turbulence, but the slower the burn--the greater the chance
of abnormal combustion. The faster the burn, the more chance of detonation
or that peak cylinder pressures are occuring too soon.

To say that low octane and high octane burn at exactly the same "flame
speed" would say that it wouldn't matter which you use.
