Use a dated Index responsibly
Write a scoped observation from a dated research release.
The Absence Index is evidence collected under a stated method on stated dates. It is not a universal leaderboard, a measure of product quality or a promise about what every buyer sees today.
Keep the denominator attached
A rate needs a numerator and a denominator. A result from one category, question set or engine should keep those labels. A company missing from a release may be outside its scope; absence from a table is not proof it was tested and lost.
Read the release before the number
Record the release date, included categories, valid-answer count, exclusion rules and what named and cited mean. Read the limitations. The September 2026 release contains 286 vendors across 14 categories and 2,095 valid answers. These describe that release, not every software company or every possible question.
Synthetic interpretation
Imagine a table says AuroraOps was named in 6 of 10 valid answers on one engine on one date. The defensible statement is exactly that scoped observation. We cannot conclude that 40% of its buyers were lost, that it is worse than competitors, or that a paid service will fix the result.
Practice, then check
Use ten minutes to inspect the public release and its method. Spend five minutes writing a source card with date and scope. Spend five minutes drafting a cautious two-sentence interpretation of the synthetic 6/10 example. Use the final five minutes to underline and remove any unsupported commercial inference.
Your learning artifact
Write a dated source card and a synthetic 6/10 interpretation. Keep your work locally. We do not use it as a company deliverable.
No real prospecting, paid measurement or company deliverable is required.
