Rappers, actors and people who feel the need to bring 5 or 6 girls on a date, that's so rare that doesn't even merit counting. And also it ends up pretty quick.
No, I mean the population of the "dating pool." For example, if a "dating pool" consists of 10 men and 1 woman, and the woman enters into a monogamous relationship with one of the men, we can say that "the top 10% of men of this dating pool are dating 100% of the women."
Only if you assume the "dating pool" is 1:1 men/women. If you take the view that it's 10:1 men/women then that conclusion is "obvious."
And at least in the context of Tinder, I have read that the ratio of users leans men.
