SH3 Commander Random Sabatage Question

[Lanzfeld]

I dont go over 16X when on patrol so it is obvious that I save alot during the same patrol because I take so long. When I want to play again I always start SH-3 Commander and "Launch" SH-3 through Commander. Is this the correct way to do it? If I had a random failure in my last game would launching again through Commander reset the malfunction? Should I only start the game through Commander when I am in port and going to start a new patrol?

You see my question is do I "reroll the dice" on malfunctions and sabatage EVERYTIME I start the game through Commander even when at sea or does it only "roll the dice" at the start of a patrol?
