For each call, there is 1 line for every 5000 packets.
I would expect the "Packet Loss" to show you the total number of packets lost out of that 5000.
The "Max Burst" should show you the longest sequence of lost packets - this is often a bunch of packets that is not received during the slight amount of time in between when one endpoint connects or disconnects and when the opposite endpoint does the same.
"Packet loss 1 Pkt" should show you the total number of single packet loss events (ie, where a lost packet was preceded AND succeeded by a non-lost packet).
The rest of the packet loss stats give you, per column, the number of times of 2-packets lost in sequence, 3 packets lost in sequence, etc...
(This is useful because the pattern of packet loss often hints at what problem might have caused it).
I think I agree with the OP.
The two columns we can see on the right add up to 302 packets lost, so the "Packet Loss" should show a minimum of "302", plus any other packets lost that we don't know about it because they aren't shown in the screen shot.
