How Gearing Effects HP from 1-3rd in 727's

Not to worry or to take my comments to heart. I recall all of the devices that came out with the 70's Arab oil embargo.... and toilet paper cartridge oil filters LOL

I am sure your tests and work will guide you better than any off-hand comment anyone can make sight-unseen. Modern electronic production FI sure made some pretty fantastic advances in engine performance.

BTW, you are right that a lot of fuel is shot into the intake when the throttle is pressed. But that accelerator pump shot is not happening when the throttle is held wide open for a dyno pass. So that theory of operation does not quite hang together. And any such results may be highly dependent on the state of tuning on the carburetor. So your 'thing' might be compensating for a very badly tuned carb, and the same results may not be there for a well tuned one.
