The bit you are not taking into account is that these are CV carbs. The slide is not connected to the throttle. The only thing you control with the throttle is the butterfly.
You can have the throttle wide open and the slide still be closed depending on operating conditions.

So when you go to full throttle the slide is not in the same position from 1000 to 10,000 RPM, in fact it is constantly moving.
One of the reasons tuning CV carbs cab be a bit tricky.
Oh ok I see now thanks for clearing that up for me it's had me confused for awhile.
