I've been reading TRP stuff and I've seen wildly variating numbers, anywhere from 3% to 33%. Could also be a lack of clarification if it's a phone number, date or getting laid conversion rate.

Bonus question. I see many people saying very few guys cold approach, but then I see some rather contradicting statements saying otherwise, or probably more specifically that hot girls get approached a lot. Do they?

EDIT: Just read a post from the main TRP sub titled "Cold approach for you PUA Sperg Dorks" and the Tl;dr: is "Don't cold approach unless you're a Chad". Now I am confused. I don't believe it though because from my own limited experience I still had at least some success.
