THE NUMBERS, EXPLAINED
How to use this calculator.
Sum duration × self-reported effort. The units are arbitrary and do not establish injury risk.
Start with your inputs
Enter session durations (minutes), perceived effort (0–10). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Session durations (minutes) | 30,40,50 |
| Perceived effort (0–10) | 5,6,7 |
A worked example
With the example inputs above, total session load is 740. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Total session load | 740 |
How this is calculated
Total session load
Multiply each session duration in a by its paired effort score in b; add the products.
Symbols and units
- a
- Session durations (minutes)
- b
- Perceived effort (0–10)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Sum duration × self-reported effort. The units are arbitrary and do not establish injury risk.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Total session load. The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Sum duration × self-reported effort. The units are arbitrary and do not establish injury risk.
Are my inputs stored or sent to AI?
Calculations on this page happen in your browser. The separate AI question finder sends its submitted conversation to OpenAI; these calculator fields are not sent. Favourites and recent tool names are stored locally. A shared link contains the inputs you choose to include.
