Work-Energy Trend Analysis

Compare work output, fatigue, and active minutes over time while accounting for coverage and reliability.

Trend analysis checklist

Use the same time window for each comparison

Check coverage and reliable minutes before interpreting

Start with summaries, then ask for relationships

Use labels to compare like-with-like contexts

Sample view

Trend first, explanation second

A work-energy read should first show what moved over time. Only then should you ask what might explain the movement.

Sample 30-day work-energy trend

Weekly averages for active minutes, fatigue load, and focus stability.

Sample data

Sample data only. Trend reads should always include coverage and reliable-minute context.

Best window: 30 days; Long enough to smooth noisy workdays.
Risk signal: W3; Sample week where fatigue rose with active minutes.
Next question: Context; Compare meeting-heavy days or deep-work blocks.

1. Trend first, explanation second

Start by asking what changed over a defined period. Do not start with “why” until you confirm there is a repeatable trend and enough reliable coverage to support interpretation.

A strong first question is descriptive and scoped: compare this month vs last month, or summarize the last 30 days and flag confidence limits.

2. Coverage is part of the trend story

Trend analysis fails when coverage is ignored. If one window has much lower reliable data, the trend can look stronger or weaker than it really is.

Ask for coverage details in the same answer.
Check whether reliable minutes differ materially across windows.
Treat low-coverage windows as provisional, not final conclusions.

3. Compare consistent contexts

“Work-energy trend” is often a mix of routines. You get more actionable insights when you compare similar contexts (e.g., weekdays, meeting-heavy days, mornings, deep-work blocks) instead of all days blended together.

Good trend-analysis prompts

"Compare this month vs last month for fatigue and active minutes, including coverage detail."
"Show my weekday vs weekend work-energy trend over the last 30 days."
"Summarize trend changes and suggest what follow-up comparison is most reliable."

4. Ask for next-step comparisons

Once a trend is confirmed, ask for a targeted comparison or relationship analysis. This is where trend summaries become operational: you move from “something changed” to “under what conditions does it change?”
