Absolutely agree Jeremy. A use case for us would be looking at the start of searching that we pass as an event and the addition to cart. By using this we can look at how changes we might make would decrease the churn and increase the efficiency of users finding what they want.

I definitely upvoted this idea. The capability looks like it might already be based in extending the existing "Time Prior to Event" dimension. The buckets might need to be a bit more granular though along with the ability to have the average.
