This is completely irrelevant. Think about it this way: In thelate 1800's Heroin was synthesised and marketed as a remedy for morphine addiction. Think about this, opiate addicts where being given a narcotic twice as potent to curb their addiction. But they didn't know that back then, so millions of people treated their addictions, coughs and upset stomachs with one of the most addictive substances known to man. It was a terrible solution to the man made problem of morphine addiction.
In this context, the man made problem is fear of rejection. The fallacious solution is routine based method. It feels like a solution, it even gives the quick fix appearance of working. But after years of working on it where can you expect to be? As good as Style? He had negligible success in terms of volume, effort put in and time spent trying to get laid. Umberto Billo on the other hand is a hotel porter who has slept with thousands of women while working a 12 hour day and looking like a paedophile Mario Bro.
What I'm saying is it feels like it works because girls respond, you get addicted to their validation when in reality you're barely any closer to sleeping with them or any other women. Go watch the Blueprint or read up on natural game from RSD. They have concepts which apply at a deeper level and actually make you a man women want, not some D&D nerd memorising lines like a script. Besides, more than half of getting laid is just being sincere. How authentic can you be reciting routines from some keyboard jockey?
