An accumulator works automatically and requires virtually no maintenance except regular cleaning. Unfortunately, accumulators are seldom seen in drag racing. That’s a pity, because they really work."

I think this pretty much sums it up. An engine builder only sees what the dyno tells them. The user sees G’s plus and minus with angle. As mentioned before hard braking can throw oil forward away from pickup and wheelies can do the same. So many combinations out there it just depends on the car and combination.
When used as a pre oiler after extended periods of sitting I think that's a great option all by itself. I don’t crank a motor after sitting for long periods , I remove the distributor and prime it. Some folks can get away with it, I can’t.
