......very tough to convince you of anything........hahahahaha.
LOL, I'm a bonehead for sure!   

But look at the red curve of Figure5 again.  This is at 3000rpm, or if scaled to an engine with a 10,000rpm power peak, it would be at 8,333rpm.  The red curve does not peak and fall off, it plateaus.  This is because once the case volume gets low enough the pressure differential gets very large, and you can no longer get ahead of the flow rate.
