Calculate CFM for moped carbs

Has anyone calculated cubic feet per minute or a similar metric for different models of moped carbs? Not sure what would need to be accounted for, intake, carb size, filter scheme, rpm?

Automotive carburetor manufacturers seem to provide this info, but I don't see anything similar on the Mikuni site for example. Is this overkill for small 2 strokes?

Does the formula for required CFM:

Cubic Inches x RPM x Volumetric Efficiency รท 3456

work for mopeds, or is there some caveat for small engines, or 2 strokes?

Are there any quirks to volumetric efficiency on 2 strokes, or does 80-85% sound right for a mild 70 build?

Not super critical, just bored at work.

Seems like the carburetor debates on here are mostly just people anecdotally declaring "that carb is too big/small for that kit", or "I have a 12 bing and my bike did 50"

Sounds approximately right to me to relieve boredom but not much more than that...
