In the past it was mandatory to indicate that you was operating outside your normal district, in this case district 4, and you also had to use the /P. This is not the case anymore.
in 2014 i used /2/P but this did not cause any problems when loading the logs to Logsearch.
I might find more strange things in the logs in the future as I am going through old logs. I think i will find logs that have been loaded twice.
