Well said Monte,
I always tell people that when they buy a carburetor out of the box, it has a calibration that will be very generic and " safe" on most anything.
You explain it a lot better than I can.
On the three versus two circuit debate, I have shown guys around here that a three circuit properly tuned will make more mid range torque and accelerate harder on the track.
The guys I have tuned them for see better shift recovery with the three circuit Dominator.
Just my experience
