While the sample winnings have their scale on the right axis, the downswing tracker has its scale on the left axis. The red area shows for any given point, how much the sample is currently away from its previous peak, meaning it tracks downswings. You can choose how many hands to simulate by moving the slider.Īpart from showing a single sample, this graph also shows some insightful information about downswings. This chart simulates a single run over 100 thousand up to 10 million hands with the win rate and standard deviation entered above. Minimum bankroll for less than 5% risk of ruin: the bankroll needed to have a risk of ruin of less than 5%.Probability of running below observed win rate …: Same as above – the probability that you will experience a run below the observed win rate over the number of hands.Probability of running at or above observed win rate …: If you entered an observed win rate, this number will show you the probability that you will experience a run at or above this win rate over the number of hands.Probability of loss after X hands: the probability that you will experience negative winnings (meaning: losses) over the number of hands.Meaning: 19 out of 20 times your actual winnings will be within this interval. 95% confidence interval: Same as the above with 95% certainty.The first interval shows absolute numbers and the second translates those into BB/100, showing the 70% confidence interval for your win rate. 70% confidence interval: Your actual results over the simulated amount of hands will be within this interval 70% of the time.The first number shows the absolute value and the second translates this number into BB/100, showing the impact on your win rate.

Standard deviation after X hands: This number shows how much your actual results will differ from the expected results on average.Expected winnings: estimated winnings over the simulated amount of hands.Standard deviation: standard deviation entered above.Variance in numbersīelow the first chart, the Variance Calculator compiles a neat list of additional information: They basically show, how much variance you should expect to see. What you need to know about them is that at any given time your winnings will be within these intervals with a probability of 70% and 95% respectively. Thirdly the calculator displays the 70% and 95% confidence intervals as light and dark green curves. This number will appear as a rather boring straight and black line in the graph. It’ll also calculate the expected winnings over the number of hands. The first thing the Variance Calculator does is to run 20 samples over the number of hands, win rate and standard deviation specified.
