Does the refuelling stop and new patrol count as a real patrol for SH3?

[Tontoman]

Did a search but didn't see this asked. I want to refuel at a different port (need the fuel I burned off on the Norway battle, 1/2 the torps left) and I get the usual NULL port when I leave. That's fine, but my worry is it's actually a new patrol and with SH3 and real life career lenght turned on, doesn't that mean I'm blowing a patrol in my career?

Thanks
T.
