Default Detonation at peak torque

I have run across several sources that state the max torque portion of the rpm band it typically the most knock prone.
I can vouch that this is a fact on centrifugal supercharged engines not originally designed for forced induction. My Mustang with a 9 lb blower always needs more retard programmed in near 4500 rpm (torque peak) than above or below.
