One thing I forgot to mention in the PM (Now that I see this is being discussed in public): The vertical scale goes up to 1200 feet, but I don't think that any WW2 ships was that big. In my opinion you could limit it vertically to 800 feet, that's enough to get a good salvo at the Yamato. By doing that and also eliminating the lines for extreme ranges you could expand the table to a bigger size and allow for better precision and extra lines without cluttering it
What format are you working with? tga, BMP? :hmm: I think I could put it in the game if you can provide a graphic in one of those formats.
