Basically, assuming 49 is the value where your Ship is at zero fatigue. Everytime you return from sortie, deduct 15 from 49 since that is the base cost for going on sorties.

Getting MvP will give you +10, that's why if a ship get's MvP twice (going through two battles in a row), (+20 - 15 = +5), your ship will be sparkling after returning to base.

Other values can also be found in the link provided.
