Added to that with increased throttle opening you get an increase in the amount if mixture in the cylinder leading to an increase in dynamic compression ratio which also increases the burn rate.
I am still not 100% on why exactly an increase in turbulence prevents detonation. If an increase in swirl and turbulence increases the burn rate will not that in turn speed at which in cylinder pressure increases leading to a greater chance of detonation.
I have read many explanations of detonation but am still not convinced
