Clinical and physiological measurement: method
20,000 leads. A mirror of an earlier study in a new direction: the
method is unchanged (40 domains × 25 axes × 20 artefacts), the subject is new.
None tested except the results page.

4. How this differs from its original
The original study asked the same questions of a different field. What transfers is the failure
structure; what does not transfer is which artefact is common. That difference is the content.
5. Limits
- Balanced grid, unfiltered.
- No prior-art check.
- Only the results page has numbers.
