In many ways, the sky is the limit with pre selection. Look at Ron Jeremy. The dude looks like an actual gargoyle, but he was preselected beyond all reason and was something of a sex icon as a result of that.
If you look better than a gargoyle, preselection can take you very, very far.
The real question is, "What can preselection do for you in principle, and when do diminishing returns kick in?"
Preselection amplifies attraction, but it can also be very, very harmful to attainability. Too much preselection will drive away all but the most confident women, or those that you have already qualified to the point where they feel highly secure. And as you ramp up the level of preselection, the marginal impact on attraction diminishes, but the lack of attainability doesn't really seem to, at least in my experience.
The worse your fundamentals are relative to her self-perception of her own hotness, the more unambiguously positive preselection will be for you. And if you have really bad fundamentals...try to go full Ron Jeremy. The better your fundamentals, the more room you have for it to backfire. It's kind of like interacting with an average chick vs a hot chick.
If a hot chick indicates that she has a lot of men are interested in her, if you're anything like me, the first couple of thoughts you're going to have are, "Great, she's happy entertaining gaggles of men, not my type", followed by, "Well no shit a lot of men are interested in her, she's hot."
Meanwhile, if an average chick indicates she has a lot of men that are interested in her, well, I probably won't care enough to ponder on it, because I'm not a woman, but if I did, the first thing would probably be... "Why are so many men interested in her? I don't visually see the reason, so it must be something I can't see."
