Equity Calculator Accuracy Test Results

Below are the results of some of the accuracy tests we use to test Poker Sleuth's Equity Calculator. For each scenario, we run the Equity Calculator 100 times and compute the error. The graphs show the error on the x-axis and the frequency of an error of less than that size on the y-axis (also known as a cumulative distribution function plot, or CDF).

For each scenario, the plot shows that the Equity Calculator's accuracy matches the design goals: errors of more than one percentage point are extremely rare, and errors of more than two percentage points did not occur.
