Credible intervals

Most statistics in poker take the form of a percentage. For example, the percentage of hands that a player raises before the flop (PFR) or the percentage of hands that a player sees the showdown. Most software provides the following single value:

When the number of observed opportunities is large, the value is a good estimate of the player's overall behavior. Unfortunately, when few opportunities have been observed the sample mean is not a good estimate. For example, suppose a new player sits down at your table and folds the first two hands on the flop. How often do we estimate how often this player sees the showdown when they've seen the flop? The sample mean is 0%0 observed instances / 2 observed opportunities = 0%, but it's implausible that this player never sees the showdown.

Instead of displaying a single value, Poker Sleuth shows you a range of percentages that the player could credibly have. From the example above, Poker Sleuth would display 1%–71%. If the player saw the showdown on 5 of their next 10 flops, Poker Sleuth would revise the credible interval to 19%–69%.

Bayesian statistics

Poker Sleuth takes statistics to the next level, by developing a profile of typical player behavior based on other players you've observed. These profiles are incorporated into Poker Sleuth's computation of credible intervals in a mathematically rigorous way. For example, Poker Sleuth may note that nearly all players see the showdown between 30% and 65% of the time when they see the flop. When a new player sits down, Poker Sleuth will show this statistic as 30%–65%. As you observe the player, Poker Sleuth will revise the estimate, slowly converging on the player's true behavior.

Table awareness

Poker Sleuth HUD is designed to make your life easier. On most poker sites, it detects when players join and leave the table and where they're sitting. The HUD updates instantly as players come and go.

When you resize a poker table window, Poker Sleuth HUD detects the resize and adjusts the positions of all its data accordingly. It even resizes the font to match the font size used by the poker table window.

Despite our best efforts to position the HUD's statistics to be unobtrusive, occasionally you'll want to see under the HUD. Simply press the Alt key to hide the HUD. Release the Alt key, and the HUD reappears.

Light weight

Poker Sleuth HUD doesn't require any additional database software, and runs smoothly even with many tables open.
