1. Compare similar weeks, not just consecutive dates
Week-over-week works best when your routine has a weekly rhythm. If one week contains holidays, travel, or unusually low coverage, ask the AI to call that out before interpreting the difference.
2. Use a two-step prompt
First ask for a summary with coverage details. Then ask a focused follow-up comparison. This reduces the chance of jumping straight into weak conclusions.
Suggested sequence
- "Compare this week vs last week for active minutes and fatigue, including coverage details."
- "Which difference looks most repeatable, and what follow-up comparison should I run next?"
3. Repeat across multiple weeks before changing your routine
A single week-over-week change can be useful, but stronger decisions come from repeating the same comparison for several weeks. Ask for trend summaries once you have a few comparable weeks logged.
