This makes little sense. Mostly because someone who does something 8 hours a day for a month is going to be appreciably better at something than someone who does it for an hour 2 or 3 times a week for example.
Not necessarily. This is because your appearance is far more important than your "pua skillset."
So you are putting a timeframe of a month and disregarding the amount of actual time someone has spent on it. Pretty sure there would be a huge difference with someone who spent 230 hours a month on this versus 8 hours.
Not really. PUA techniques have been taught and practiced as such since at least the late '90's and was especially popular from say, '05 to the early 2010's.
That means there have been "instructors" who approached multiple days a week, multiple hours a day, for a decade or longer whose results we can evaluate. Who's the best out of all of those instructors? Probably Neil Strauss. Yet, his best results were the types of women sosuave finds disgusting: purple hair, drug abusers, party lifestyle with high body counts: basically, pump and dump rocker chicks that Neil took on as reclamation projects.
The rest never divulged their results, likely out of embarrassment. Their business models if you could even call them that were destined to self destruct for a whole host of reasons but they got rich in the meantime.
Everyone has a ceiling to how good they can get but at the end of the day they need to dedicate sufficient time and also focus on the areas they are weakest in to gain maximum benefit from it.
A 4' 9" horse jockey can practice trying to dunk for the rest of his life and he'll never succeed. Even the very best women's basketball players rarely dunk and even then they can barely dunk.
Heck, even most grown men in their 20's can't dunk. (As an aside, look up the name Pat Conaughton. He's a white nba player, and I believe he has the highest recorded vertical in an NBA combine. However, he couldn't win the nba dunk contest even though he had the genetics to make him the best leaper in the entire league? Why? He didn't have the reach or the hand size of the other top dunkers. A "genetic limitation" if you will. Add to that, he's probably a below average nba player).
Back to picku: if the "top instructors" can only pull emotionally damaged rocker chicks who mutilate their bodies then what type of success can their nerdy, socially awkward clients expect?
You are talking in a vacuum. But I can point to the history of the PUA movement and show that it was basically fraudulent even with instructors approaching women as a full time job.
