Interpreting Performance Stats - Jitsi Metrics

When viewing the Grafana based Jitsi Metrics we are seeing Audiochan and Videochan numbers not match. It looks like a previous conference was not torn down completely as we have seen a single conference on all day so far with one participant.

Question: Should Audiochan and Videochan numbers typically move in lock step. We do not offer an audio only participant at this time.
