Quantifying variance - what's the standard deviation of winrate per hour at live 5/10?
One thing to consider here is the central limit theorem . Basically, when you sum many values from the same distribution, the result will be approximately normal. So, even if your results per session are not distributed normally, it may be the case that your annual results are. Your results per hand are not going to be normally distributed (one simple way to see that is that you can triple up, but you can only lose 1 buy-in, so it's not symmetric). I would also not assume that your results per session are normal, even though they are a sum of hands. The reason is that the hands are not independent, because the results of one hand affect your stack size for your next hand. More on reddit.com

r/poker on Reddit: Need help understanding variance calculator
March 3, 2024 -

This is an incredibly small sample size I know. Just started playing 1/3 this year after mainly playing online tournaments for fun. I’ve been studying diligently and trying to apply what I’ve learned at the table.

I just do not understand what the graph and results are telling me. Any help would be greatly appreciated.

Currently at 58BB/100 @1600 hands which again I know from reading this sub is a minute sample size. Just looking for some insight into the graph/results.

you dont plug in your winrate after 1600 hands into a variance calculator- you learn nothing from this What u should be doing is play around with different winrates and see what the expected downswings can look like so you can prepare urself

It calculates confidence intervals for your true win rate analytically as well as calculating potential graphs via simulation. In this case it ran 1000 simulations, and the worst graph in that set of 1000 simulations was the dark brown one and the best one was the blue one. However the light and dark green quantiles are smooth rather than stochastic because they are calculated analytically using the observed win rate (58bb/100) and standard deviation (119bb/100) that you input to the calculator. 58bb/100 is an unbiased estimate of your true win rate but it’s a very noisy estimate. The 95% confidence interval means that under repeated trials of 1000 simulations it will cover that true win rate 95% of the time. It also provides a similar probability calculation of 97.44% of having an observed win rate better than 0bb/100 if your actual win rate was 58b/100 if you ran a new simulation. It’s calculating the confidence interval for every single time point. You want to compare the confidence intervals for your observed win rate (58bb/100) under different standard deviations. In theory full ring games should have lower standard deviation than heads up or 6max but that’s probably not the case in cash games that are so soft you can win 58bb/100. If you want a very conservative estimate of the uncertainty of your win rate you should try standard deviations of 150 or even 200 if that’s a good description of the games you play in.

We might ask: What is the probability of selecting exactly 3 red cards? In this example, selecting a red card (a heart or a diamond) would be classified as a success; and selecting a black card (a club or a spade) would be classified as a failure. Using the hypergeometric calculator, you can compute this probability.
