Calculator Inputs
Score each window from 1 to 10. Higher energy, focus, and motivation improve the result. Higher stress lowers the peak score.
Example Data Table
| Window | Time | Energy | Focus | Motivation | Stress | Interpretation |
|---|---|---|---|---|---|---|
| Morning Prime | 08:00 - 10:00 | 8 | 9 | 8 | 3 | Excellent for deep work and planning. |
| Late Morning | 10:00 - 12:00 | 7 | 8 | 7 | 4 | Great for analysis and writing. |
| Early Afternoon | 12:00 - 14:00 | 5 | 5 | 5 | 5 | Better for meetings or lighter work. |
Formula Used
Peak Score = ((Energy × 0.40) + (Focus × 0.30) + (Motivation × 0.20) + ((11 - Stress) × 0.10)) × 10
- Energy carries the largest weight because stamina drives output quality.
- Focus strongly shapes accuracy and concentration during demanding tasks.
- Motivation supports follow-through and reduces friction during work.
- Stress reduces usable capacity, so the formula reverses its effect.
- Consistency Score = 100 minus a scaled score spread penalty.
- Strain Index = average stress rating multiplied by 10.
How to Use This Calculator

- Rate energy, focus, motivation, and stress from 1 to 10.
- Submit the form to calculate weighted peak scores.
- Review the best window, backup window, and recovery window.
- Use the chart and table to compare performance patterns.
- Download the results as CSV or PDF for planning.
FAQs
1. What does this analyzer measure?
It measures the relative strength of each time window using energy, focus, motivation, and stress. The result helps you schedule difficult work when your natural capacity is highest.
2. Why is stress reversed in the formula?
Stress usually reduces usable mental bandwidth. Reversing its effect rewards calmer windows and prevents a high-energy but overloaded period from appearing stronger than it really is.
3. What is a good peak score?
Scores above 85 suggest a strong deep-work window. Scores from 70 to 84 suit important tasks. Scores below 55 usually fit lighter work, breaks, or maintenance tasks.
4. Can I use overnight time ranges?
Yes. If an end time is earlier than a start time, the calculator treats the window as crossing midnight. That helps users with night shifts or late study sessions.
5. What is the consistency score?
It shows how stable your performance stays across the day. A higher value means your windows are more balanced. A lower value suggests sharper peaks and dips.
6. What is the backup window?
The backup window is the second-best scoring period. It is useful when your top slot is unavailable or when you need another focused block later in the day.
7. How often should I update my entries?
Update them daily for short-term planning or weekly for trend tracking. Repeated use helps you discover reliable patterns instead of reacting to one unusual day.
8. What can I export from this tool?
You can export the ranked result table as CSV or PDF. That makes it easier to save records, share insights, or build a longer planning history.
