+1 accuracy ~ +1% hit rate

+1 damage = +1 damage (most of the time)

Against a Ri Flagship with 70 armor assuming a 80% accuracy rate base and below cap attack,

+1% hit rate will give (81/80-1) = 0.8% more chance of sinking.

After Ri-chan's armor range of 47-94 (i.e. a range of 47), +1 damage gives 1/47 = 2.1% more chance of sinking.
