[Corsair]

I find that if I am submerged 2 knots it doesn't have time to change much and anyway don't need to have a 1° precision if you shoot at a normal 500 / 1000 m distance.
Whenever possible, I try to shoot a 90, so I don't even take a measure of the AOB 90% of the time.
In my game also I have sliding TDC dials on the map screen so don't need to change view to enter data. I never use the notepad.
