carbureted throttle / gear possition

When I was on the highway the other day I noticed in 6th gear on my carbureted bike I was using more throttle than in 5th gear for the same speed.

This got me wondering which is better. A smaller throttle position or smaller RPM

my gut reaction says RPM but knowing how carburetors work I am unsure as i don't know how much gas + air mixture is being taken from the carbs and in what ratio at a bigger throttle position with lower rpm vs a smaller throttle position and higher rpm.

Is RPM king? And could anyone explain why this is the case?

been a while since i've messed with a carb, but as they work more or less off of airflow, i'd say that unless you're far enough into the throttle to start activating the power circuit, you'll do better in 6th.
