Here's a question: I've been trying to use the guidelines and the tick marks on them to help. Its seems that with most of the IJN and US ships (not many since I do SS and CV except for AA) I use that at higher angles the tick marks are 2 degrees apart but at some point below 23-25 the tick marks change to 1 degree apart. I've been experimenting with that and trying to nail down some consistancy and just wondering if there really is a pattern that can be followed?
