Should you have any questions, encounter any errors or have ideas for improvements, please let me know. In general these simulations underestimate the extent of downswings, but the numbers should still give you a decent idea of the vastness of downswings you should expect. Meaning, by this definition a downswing is not over until the player has fully recovered its losses. For the purpose of these calculations a downswing is defined as any period where the current total winnings are below the maximum previous total winnings. For example (50000+ Hands – 15.81%) means the simulated player was in a downswing over at least 50,000 hands 15.81 percent of the time. For example (1000+ BB – 31.77%) means the player was in the middle of a downswing of at least 1,000 big blinds 31.77 percent of the time.The second table shows how long downswings last on average. It shows how often the simulated player was stuck in a downswing of at least X big blinds. Therefor 100 million hands are simulated and all downswings over this simulation are tracked.The first table shows the extents of downswings.
