This feature is particularly useful when a user performs the same action multiple times, before moving on to the next.
For example, if a user searches for a cab multiple times between 10:00 AM to 10:05 AM, before booking, then you can add your interval as 5 minutes. These multiple events are grouped and counted as one event.
With the Intent count metric, the users can group events with a unique intent. One can choose the time intervals (ranging from 1 minute to 60 minutes) to group them.
