How many games to figure ROI?

[DJSHAD0W]

How many games do you think would it take to get (reasonably) close to your true ROI at a given level?
(within a few % up or down)
50 / 100 / 150 ... more?

Check the FAQ. Short answer is at least 500.

Your ROI will be 90% certain after 4,000.

To put it in perspective, think about all the times your KK ran into AA when the possibilty of that happening is around 3%. Now realize that after 4,000 of these you can only be 90% certain of your ROI.

4000 every level.... that's a lifetime if you don't play full time.
How did you come up with the 90% after 4000 games?
Whats the accuracy after say 200 games?

Thanks.

Just because 200 sounds a lot, it doesn't make the confidence change.

I just calculated my confidence for my results at the $55s thus far. Just to give you an idea.

After 563 sngs:

I can be 51.03% confident that my true ROI is +/- 5% from my current ROI.

So, you can see that it takes considerable more than 500 sngs to have any degree of confidence in your ROI.
