Writing for an audience of tool developers considering or pursuing integration, explain what thresholds are about, how to select target parameters, how to calculate the thresholds, and how to use that number.
Develop image and table assets. Use real-world wiki configurations as contrasting examples.
Maybe rely on existing explanations of the general problem, e.g. https://stripe.com/radar/guide
One more important detail to document is to explain why different threshold optimization functions are used in various use cases, aside from just the threshold itself.
"Worked example" should probably be included before we consider this draft complete.
Maybe there's some useful insights on what this doc should look like before we call it {{done}} here: https://www.mediawiki.org/wiki/Technical_Document_Re-working_Group/Resources
