Question About Refuel / Refit Stops

Hey guys!

For now I'm still based out of Pearl, just now heading out to Truk on my second patrol. In case you haven't noticed there's a LOT of blue space between Point A and Point B. It's my own personal "thing" to make a port call at the closest place to my patrol area to top off the tanks.

Over the course of the patrol I make lots of visits to refuel and rearm. Does this have any affect on my renown? I mean if I can complete the patrol with only making a couple pitstops would I have a higher score than if I make four port calls...assuming I'd sunk equal tonnage.

Just wondering...
