No, we ARE on the same page, you just haven't done the math.
With 4 6's, you've already inflicted enough hits to be just shy of its critical armor rating anyway.
actually her vital is 13, nowhere near shy with only 8
Which means, its weakness... is what killed it historically- a well-placed salvo from heavy guns can blow it to fragments.
And at Range 4, the Scharnhorst isn't going to do that short of some miracle.
umm, yeah it is, its called rolling dice, and as well all know dice will do that, heck I've vitalled Bismarks, scharnhorts, Iowas, washingtons, Rodneys and Yamatos with single flights Dauntless Dive bombers on a regular
and with 11 dice at range 4 the Scharnhorst has an 88.67 chance of getting 4 6's, thats pretty damn high odds
and in reality a Horst doesn't have the Caliber of gun to do it, and under that range no ship would have the angle to do it either, it should of been a rule left only at range 4+ or to only the Bismark
