Finally managed to run an in-game test without the clever AI spoiling later reload test results by SRing away the units I want to attack.
So, with 3 corps of ARM-7 (3 divisions/corps) I attacked same 3 brigaded Vichy units 3 different times.. first using 1 corps, then 2, and finally 3.
3 ARM-7 (-33 stacking penalty) took 32 hours to win. 6 ARM-7 (-50 stacking penalty) took 21 hours to win. Both corps had same terrain modifiers.
Finally, 9 ARM-7 (-58.09 stacking penalty) took only 14 hours to win. And that is with the extra armor corps having additional -40 river crossing, but - because 3rd angle of attack - all units get +10 multiple fronts.
In its simplest analysis, it shows that "stacking penalty is irrelevant" because it is simply the side effect of gathering a bigger attack force. You win faster with bigger stacking penalties - not because stacking penalty is good - but because bigger stacking penalty means a bigger force (which then is what wins faster).
