Take your dick size in inches and divide by 2.

Add that to your height in inches.

If the total is under 72" / 6', just rope already unless your face is 10/10.

Between 72-76 inches is 'she'll still cheat when she finds better' territory (or betabux / soyboy).

77-83 is chadlite - chad equivalent regardless of face. You have enough height and dick that a roastie won't care what you look like (put on a mask and BDSM max).

84+ is gigachad territory. Roasties won't even care if your face is burned off as long as you hide it.

Now have fun making calculations and getting dick mogged by a calculator. Braincels would ban calculators if they see this.
