Listener statistics show more listeners than listener limit

Question:

I notice that in my listener statistics, some hours show more listeners than the listener limit for the stream. How is this possible?

Answer:

Centova Cast's listener graphs display the total number of distinct listeners (not simultaneous listeners) in a given hour. So for example, if one listener tunes in, then disconnects, and then another tunes in a few minutes later, this is considered two listeners.

We feel that the hourly distinct listener count is a more valuable metric than hourly simultaneous listeners, given that you already know the maximum listener limit for the stream.
