Practice session
A run of decisions with no break longer than 30 minutes, used to see whether accuracy fades as a session goes on.

- What it means
- The stats split your decisions into sessions wherever you stopped for a while. Each decision then knows how far into its session it came, and what time of day it was made.
- How it is calculated
- A new session starts when more than 30 minutes pass between two decisions. Days that have been rolled up into daily summaries have no times, so they are left out of the session and time-of-day views.
- Worked example
- You drill 40 spots from 9:00, stop, and drill 10 more at 19:00. That is 2 sessions: decisions 1 to 25 and 26 to 40 of the first, and 1 to 10 of the second. If accuracy is 85% in the first 25 and 70% after, your focus fades after about 25 decisions.
- Why it matters
- Tiredness and tilt show up as a drop late in a session or at one time of day. Seeing it tells you when to stop, or when to practice.
