Miller,
I know you're probably not referring to me on feeling of recoil reduction on forcing cones, and I never could feel anything about that either. But, I have done long cones on several guns for what I believe to be pattern improvements. In my very small test, I saw what I believed to be pattern improvement. Until someone shows better evidence to the contrary, I'll stick with my story.
But back to the calculation of the the effect of muzzle breaks. It seems to me that pressure would have more to do with the effectiveness of a given break than the payload velocity. Once the payload leaves the barrel, the hot gases/powder escape at velocities much higher than the payload. So I believe a very slow payload with an extremely high pressure could reap comparable benefits or better than a light, high velocity payload with moderate pressures.
