An ATC with VTO summary may use all VTO sessions as its denominator, while Add-to-cart rate in the PDP cohort uses product-view sessions with VTO. Both can be correct because they answer different questions.
Every dashboard tooltip should identify the numerator, denominator, unit, and whether the metric is exact or directional.
