Mental game

How your state of mind, such as tilt, tiredness or focus, changes the quality of your decisions.

What it means
The mental game is everything off the cards that affects how well you play: frustration after a bad beat (tilt), fatigue late in a long session, or being fully focused.
How it is calculated
On the stats page you tag each session as focused, tired, tilted. A session is a run of decisions with no break longer than 30 minutes. The page then compares the EV you lost per decision under each tag.
Worked example
Over 300 focused decisions you lose 0.05bb each; over 80 tilted ones you lose 0.18bb each. Tilt costs you more than three times as much per decision, so stop when you notice it.
Why it matters
It is easy to believe you play the same when tired or tilted. Your own numbers by tag show how much it costs, and when to quit a session.
