How many entries do I need?

Your score appears from your first entry. There is no minimum required to see a score, but with only one or two entries the score is just an early read and will move significantly as you log more.

Pattern flags (high cancellation rate, hot and cold cycles, breadcrumbing, and so on) need at least three entries before they start firing. This prevents one bad day from getting flagged as a pattern.

The more you log, the more accurate and stable both the score and the patterns become. With 15 to 20 entries, the score is a solid reflection of the recent behavior.

You can also adjust the time window using the filter on the score view (7 days, 30 days, 90 days, or all time). A shorter window gives you a snapshot of where things are right now. A longer window shows the bigger pattern.
