Sorry, I missed this question earlier. When speaking to the external device, each UDP command packet that's sent should be balanced with a response. However, if a UDP command is sent to a device that's not on (or there's a typo with the address) then obviously that transmitted packet will never be responded to. I expect something like this could easily have happened during the session in which I ran that test for you, so in that case would be explainable. I note that the difference did increase to 7 at the 1447985726.272550987 mark. Since this was during the test I can't quite explain that one, unless something else on the system happened to send a UDP packet out onto that interface which was not responded to.
