I think it is more aligned toward fpe (equivalent gas burners and compressed air), allot of airguns despite caliper have different fpe output. Like an under powered 30 caliper would hit at 90 fpe. Standard .25 daystate airrangers do 40fpe, then there is one that does 60fpe, I have the extreme that does 80fpe and after I put on a 1.1l bottle it is going at 90fpe which helps push the .75" 57 grains slugs submoa down range. Also you have non regulated airguns (stores in plenum) that full mechanical, electric controlled fire sequences and ones with multiple onboard regulators (fx). Sorta a complex bunch of inputs to standardize. The size benefit of 30 caliper verse 22 is .04" benefit which wouldn't really be enough meat to score the hit anyways. Heavy slugs drop faster, so it is all a matter of doping. While heavy bucks the wind more, they are in the air longer, so wind drift is more too.
So I'm thinking all things being equal there are allot of options airgunners have to compete with the rimfire, obviously higher end airguns yield close to air superiority over those powder burners
