If looks are so subjective, then how do we know that a couple are of similar attractiveness?

If we can distinguish this difference from others, then how is the blackpill or looksmatch incorrect?

I only mention this because I see this counterpoint a lot, but I personally don't get how this is comforting.

The problem with men like myself is our looksmatch would rather wait and find a better man or stay single then stoop to our level. Even if we are of similar attractiveness, always aiming up.
