You may have the wrong dpstick installed from the factory, the dipstick tube may be the wrong length, or the usual tolerances of dipstick tube length, dipstick mark location, and dipstick overall length may just be stacked unfavorably for your vehicle. And besides, for most vehicles it takes a LOT of over-fill to actually make the crank get close enough to the oil pool to cause aeration and foaming problems.
I respect your opinion, but it's important people understand your view is at odds with auto manufactures.
