Sample Size

[Killerkilsby]

Hi All,

I know we always talk about a big enough sample size to get an accurate ROI, however I am interested in what this number would be in the following examples:

18 man Sngo's?

45 man Sngo's?

Are we talking over 1000?

well over 1000 esp for 45's

As a guess for 18 and 45 mans:

100 games: Within 15-20% (sample size incredibly irrelevant)

500 games: Within 5-10% (still somewhat irrelevant)

1000 games: Within 2-4% (Getting there)

5000 games: Within 1%

I'm guessing here but it won't be far from the truth. The problem being is that the games are always changing and the person in question might be improving slower or faster than the games which would mean that they might not ever be playing to their ROI in their sample size.
