I'd love to see cohort reporting.
Conversion rates are cool, but time to convert is just as important if not more important.
Cohort reports would help us report on that.
Questions I'd like to answer:
How long does it take for deals in stage 1 to get to stage 3 and what % of deals are going through these steps. Is this different for different sources.
How many have their first conversion until a deal is created for this contact. How long does it take and is that different for various sources?
