I am sorry that my comment may confuse you.

>34(Roma's 件数)/(2226(all dropped ships at S victory(=sum of "S" for each ship)) + 2226(Probable non-drop at S victory)) = 0.76

This drop rate indicate, the pecentage of "the possibility of dropping Roma at K node if you get S-victory at K node under the assumption that non-drop and drop is half and half".

 the pecentage of "the possibility of dropping Roma at K node if you get S-victory at K node and ship is dropped" is still around 1.55%.
