All right, the tool works as expected and I really can't add much to what I said before. The new scales help much with the shorter/medium shooting distances, which are the most used ones and everything else is OK. If anything, more subdivisions in the torpedo run time to run length would be nice, but there really isn't much more space for it :hmm:
Anyway, I suspect that a slide ruler would be the perfect tool here. If you can think about something along those lines, I *think* that I can provide a dirty but effective method of bringing it in-game, using a fixed background image and then a draggable one you can move along the first.
If you are happy with this as final version, just tell me and I will do an in-game version ASAP.
Cheers
