Read Completion Rate
Calculate read completion rate from the supplied measurements.
Description
Read-completion percentage compares consumed article depth with the full depth.
Read-completion percentage compares consumed article depth with the full depth. The units cancel only when both measurements use the same basis.1
Calculate read completion rate from the supplied measurements.
When to use Read Completion Rate
Use this tool to calculate read completion rate from the supplied measurements.
Prepare the text, recorded observations, aligned figures or editorial criteria requested. Confirm what each label, count, timestamp or supplied flag represents before interpreting the result.
How to use Read Completion Rate and understand its results
- Prepare the text, recorded observations, aligned figures or editorial criteria requested. Confirm what each label, count, timestamp or supplied flag represents before interpreting the result.
- Enter consumedDepthPixels, articleDepthPixels using the field table and calculation rules, then run the tool.
- Read completionPercent. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| consumedDepthPixels | Consumed depth | number | Required |
| articleDepthPixels | Article depth | number | Required |
Enter finite depths with nonzero article depth. The shared ratio helper returns a percentage and permits signed values or values above 100.
completion%=100×consumedDepth/articleDepth Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| completionPercent | Read completion (%) | number |
{
"input": {
"consumedDepthPixels": 1800,
"articleDepthPixels": 2400
},
"output": {
"completionPercent": 75
}
}Limitations and assumptions
No scrolling, reading behavior or attention is measured. Use a positive physical denominator for interpretation.
Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
