Note that the timelines do not report the amount of channel bandwidth wasted due to collisions, as the TNCs (software or hardware) do not report collision intervals. It is unlikely that a channel is capable of exceeding 50% capacity unless a strict discipline such as timeslotting is used by all stations to avoid collisions.
If the expert-mode Configuration dialog's Behavior tab specifies that Aloha circles should be calculated for the APRS-IS feed, then a tab will be added here to display the received APRS-IS traffic. Note that the timelines for APRS-IS may show considerable (and incorrect) packet overlap, as the Internet can usually send packets much faster than the normal 1200-baud VHF channel, especially for a feed larger than the local RF Aloha circle.
