40/100 Thin
Scores higher than 80% of 577 entry-page captures we have measured. Among the 311 saas funnels in that group, higher than 68%.
Walk 106 links seen, 95 walkable, and 0 matched a funnel step. If this funnel continues past the entry page, we did not reach it — everything below is measured from the entry page alone.
How this was measured
Measured by Roentgen 1.20.1 on 2026-08-09. A capture is read once and its measurements freeze there, so the stamp says which ruleset read this one.
Coverage is detection coverage, not a verdict — it counts the conversion tactics we could prove are present, out of the 11 that apply to a saas funnel. Per device: desktop 40 · mobile 40.

Absence is a measurement, not a recommendation: we do not know why a tactic is missing, whether it belongs here, or whether adding it would change anything. Where a walk stopped early, a tactic living deeper would also read as not detected.

We ran these passes on the pages we captured and found nothing to show. That is a measurement of this funnel, not a recommendation — and it is a different statement from a layer we never ran, which does not appear here at all.
