In terms of what's possible, it's mainly to do with the variables. That's why it's kind of a pointless discussion. Because it's the variables, some of which aren't in our control, that makes it possible
What I will say is that I agree with
@Bigpapa in terms of what's possible. For example, I think a very good looking guy (my wingman for example) living in a party destination like Vegas or whatever, AND with dropping his standards and going for any girl who passes the boner test and not just girl who are his type, could surely get laid basically every night.
But
@mikedee is of course right in that most of these PUA's are living in a fantasy world and are making claims for marketing/money reasons. Plus of course banging absolute dogs (blurred faces but you can see they're chunky and/or old) and celebrating it like a super bowl win
And yes, SOME of the numbers i've seen quoted (some by people on this forum who I won't mention) probably ARE complete fiction. I've seen some insane numbers thrown around lol. Numbers that even my wing couldn't match and I don't think for a second anyone here could compete with him.
The Asian dude in question is likely talking BS about his 147 if I had to guess. (probably more like half that, and not forgetting that the quality would be very unimpressive)
Since nobody's really answered this for you, i'll give you my response.
I don't think it's the best method personally. I have nothing against super direct guys, but I don't feel it's the best method.
I'd suggest something more observational/situational, making some small talk, adding a touch of flirting, and then escalating all the way. That's as simple as I can simplify what I think is the best method, and it's probably also a simplified version of the way most indrect PUA's do it.
BUT, what you are asking about is SO simple, that you should just go out tonight and try for yourself! lol. It doesn't take any skill. You already know what to do and say. There's nothing to 'learn' - (That's why I laugh how such direct guys dare charge money for bootcamps etc!!) Try it. Go out tonight and stop girls, tell them you noticed them and think they're hot as $hit, and see where it goes. You'll come to your conclusion soon enough
However, i'd also concede that there's just not THAT much in it! The 'method' you use isn't going to effect the numbers over a large enough sample. What really matters is, is she attracted to you! And even indirect game with all of it's negs and dhv's and rules and lines doesn't cut any ice when the answer is a hard 'no'
