And that begs the old question: are the game errors just plain sloppiness on the part of the devs or purposeful helter-skelter to make our lives more interesting?
After all, a 25% error in the mast height translates into a 25% error in range. A ship measured at 4000 yards could be at 3000 or 5000 yards (depending on whether the game masthead number is 25% too high or 25% too low), a deviation of 2000 yards.
Seems like the easiest way for that stadimeter to work would have been for it to grab the masthead height from the game's working parameters, not a separate and wrong table. That makes it seem to me that the errors are purposeful for some unknown purpose....something like that.
