A chad don't need to approach 100 above average single women. He's not a AFC/average dude to do numbers game like that. Sure, they definitely take the initiative more often, but that's because he already passes nearly all of the short term threshold that women require from a man. So his success rate will be threateningly high when compared to average men.

But anyway, to answer your question:

dating apps: Probably 10-100+ right swipes a week.

nightclub: if he's able to bring home a girl more than 4 out of 10 times he goes out.

social circles: If he's able to hookup with nearly all the girls he hangs out with.

School: Usually about 1-3 girls a week on and off. I know a dude who used to have, like, 12 girls on rotation during his final year. Its literally a fuckfest in that dorm.

Work : I don't know and I don't recommend workplace romances.

Community events are usually not that frequent so its harder to give accurate answer.
