I just noticed a small detail that could be revised in the future (It's a detail by I tend to use a lot those markings and it makes things a bit more difficult): In the inner ship silhouette dials, the own ship one goes from 0-360 correctly, but the target one also does the same. In the real TDC it went 0-180/0-180, because it represents AOB at the marked point (Line of sight to own ship).
