What gets counted
How often a theme recurs in your approved memories, and which periods resemble each other in their positions. It is a count over your own text.
My life / Your observatory
Patterns
Recurring themes in what you recorded, and comparable periods.
A pattern is not a prediction
That something recurred three times says it recurred three times. What happens the fourth time is not there, and Astrae makes no claim about it.
Little material, little pattern
With a handful of memories there is nothing to count. Astrae says so, rather than showing a pattern resting on three points.
