85/100 Strong
Scores above 95% of 1,252 multi-step funnels we have measured. Among the 959 saas funnels in that group, above 94%.
How this was measured
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 85 · mobile 85.
Measured by Roentgen 1.7, one of our versioned rulesets. A capture is read once and its measurements freeze there, so the stamp says which ruleset read this one.

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.
