Default Re: How fast do different PFR% converge?

Intuitively this doesn't make sense to me. Logic would seem to dictate that if we had 1326 ping pong balls and 47 of them were red (but we didn't know they were red). It seems like we would have to take many more samples from the group to get an accurate representation of those red balls, especially if in some light the red ball appeared to be white...


Now suppose that 663 of the balls are red. If we were to take samples from that group it would converge toward actual much faster. Atleast that is how I picture it working in my mind.

It seems like the bigger portion of the population the test group you are trying to get information about is, the less trials it would take to get an accurate representation of that group.
