To answer your OP. Simply put - carbs are designed to deliver a metered flow through-out the RPM rand and load of the engine it's feeding. The capacity of the float bowl is really the key to keeping fuel supplied under all conditions. The float level in my experience can be slightly above the spec or below and the carb will still function correctly.

When setting any float - again my experience - I set just below the spec. I want to make sure the float bowl is not over filled. This prevents fuel spillage out of the vent during hard acceleration or cornering. What ever the application - you can bet the fuel pump and pressure line size is more than adequate to provide both flow and pressure to the carb as it was all designed. So the float could be set on the low side of volume - (less fuel in the bowl) but you'd never see any difference as long as everything else is functioning as designed.
