There isn't a widely accepted standard for PSL ratings so is my interpretation of the rating scale that makes the most sense to me.
PSL ratings go from 1-9
1 is alive but severely deformed the lowest rating approaches 1 so nobody can be a 1. Only a 1.0000...1
9 is nonexistent, the more ideal the man the more his rating will approach 9
Follows a normal distribution so the majority of guys will be withing the 4-6 range
4 is 20th percentile
6 is 80th percentile
Alot of male models aren't all of a high 8+ PSL rating since it takes into account sex appeal to women which some may lack.
Some raters choose to take into account height and frame while some don't. (I do because it is important for presence and sex appeal)
Subhuman (bottom 20 percent) are sub 4
Low tier normie = 4
Normie = 5
High tier normie = 6
6+ is chadlite
7+ is chad
8 is wide appeal gigachad who has access to pretty much all women
8-9 is where we begin to approach the singularity and things get wild, It's the equivalent of being a multimillionaire (low 8's) to a billionaire (high 8's). The sexual market flips to your advantage girls will begin treating you like a celebrity, you will get random catcalls on the street and random women will throw themselves at you aggressively,
