The 1 in 50 number was totally pulled out of my ass
That seems to me to be a less appropriate way to do things on LW, personally.
Certainly, arguing that you pulled a number out of your ass in order to refute empirical information providing an inside view of a phenomenon is really inappropriate here.
IOW, your hypothesis is based on a total and utter incomprehension of what PUAs do or value, and is therefore empirically without merit. Actual PUAs are not only aware of the concept you are describing, but they most emphatically do not consider it success, and one guru even calls it "fool's mate" in order to ridicule those who practice it. (In particular, Mystery ridicules it as relying on chance instead of skill.)
In short, you are simply wrong, and you're probably getting downvoted (not by me, mind you) not because of disagreement, but because you're failing to update on the evidence.
Followup to: Do you have High-Functioning Asperger's Syndrome?
LW reader Madbadger uses the metaphor of a GPU and a CPU in a desktop system to think about people with Asperger's Syndrome: general intelligence is like a CPU, being universal but only mediocre at any particular task, whereas the "social coprocessor" brainware in a Neurotypical brain is like a GPU: highly specialized but great at what it does. Neurotypical people are like computers with measly Pentium IV processors, but expensive Radeon HD 4890 GPUs. A High-functioning AS person is an Intel Core i7 Extreme Edition - with on-board graphics!
This analogy also covers the spectrum view of social/empathic abilities, you can think about having a weaker social coprocessor than average if you have some of the tendencies of AS but not others. You can even think of your score on the AQ Test as being like the Tom's Hardware Rating of your Coprocessor. (Lower numbers are better!).
If you lack that powerful social coprocessor, what can you do? Well, you'll have to run your social interactions "in software", i.e. explicitly reason through the complex human social game that most people play without ever really understanding. There are several tricks that a High-functioning AS person can use in this situation:
