It’s very simple, I think it works, but I’m open to ideas and any form of help to actually make it work.

@delusionalwino, but in his size formula, he has (S times 2) where size is the variable (5.1 inches) and 2 is a constant. In his rpm formula he has 1R=2sec, where 1 is a constant and R is the variable.which doesnt make sense unless you multiply rpm by a unit of (second per rpm) to get a unit of seconds as a final answer.In his equation , he never filled in the R value and instead puts in 2R, which by the way, where does the 2 come from?

@LightskinDarkNig, I would change the rpm unit to seconds per full stroke(spfp.) So 1spfp=2 seconds to do 1 full stroke. In his equation, he has written 2R when it should just be 2 seconds. The math checks out in the end if you substitue time to 2 seconds and comes out to 10.2 inches. So the final answer is indeed 0.05795 miles.

@slapmysalami, I like the idea of changing the unit to spfp. I wrote the equation pretty quick and I’m not a mathematician by any means. Having the unit be spfp makes more sense. I’ll make note of it, also I wrote the equation with a lot of averages and assumptions, to make it so I could show the math. Thank you everyone for the support and feedback!
I got about .0579miles per blowjob. Can someone confirm?.
