Customer Purchase Latency is a measurement of the delay between customer purchase events (orders). It's in the form of a time, usually a number of days. So a 30 day Customer Purchase Latency means 30 days pass between orders.
This is usually aggregated across all of your customers into Average Customer Purchase Latency.
