I have recently started listening to audiobooks and courses made by leading members of this community like Neil Strauss(Style), Tynan(Herbal) and "Tyler Durden". They are really at the cusp, the vanguard of sociological and psychological research, since they are not passive observers merely making theory, but intervening and using it to get women. What you are doing is misrepresenting things probably because you are just listening to ignorants on some webforum.
Women generally do not like the obvious guys that hit on them. While they like the attention, and feeling wanted, such guys lower their social value by appearing to want badly to impress or hook up with her. Instead contrary to what you said, you need to present yourself as a cool, comfortable guy who has a good time and is not obviously looking for a pickup. A good way to do this is to immediately disqualify yourself by saying you are not available, you live too far, she is too old/too young, she reminds of your sister, etc. An additional tactic is to "neg her" by giving a backhanded complement that is mixed with a slight insult. Another thing you have to do early is to get physical with her early by non-threateningly tapping her shoulder and such, like her female friends would do, so you establish physical contact, comfort and rapport early. You also have to convey enough of your personality so she feels she knows you even though you may have only spent an hour or less with her. If you do things right by demonstrating a higher social value, and that you are a good time to be around she will want to be with you.
Further you whole pegging of alphas is incorrect. It is not alphas per say that women are attracted but those who demonstrate higher social value somehow. Many musicians are not alphas, they are usually contemplatives, but they get women because since they are in a band, they have a social value that women want to attach themselves to. There are different terminologies of guys that just get women, one is a "natural", the type of guys who do not know PUA formally but know it anyway more than many PUA practitioners. Another type that gets women often is the rich daddy type who has alot of money he flaunts, but they usually trigger the provider instinct of a woman and get played into the pathetic role of bribing female attention with their gifts and wealth. Sometimes alphas do get women, but also they can be way too aggressive to make women comfortable.
