Weird or not ?
My current patrol:
Jan 1st, 1941. Latitude at midnight: 40°.
SR/SS Almanac from the mod says that I should get a SR at 7:22 local time for 40°N and 7:58 at 50°N.
By taking speed (10.5kn) and course (000°) into account, my position at SR would be at lat. 41,5°N.

Difference for SR times from 50°N to 40°N: 36min
1.5/10 * 36 = 05:24m.
So SR at 41,50° would be at 7:27:24.
7:58:00 - 7:27:24 = 0:30:36.
0:30:36 / 1.5 = 20.333...
which is my current longitude.

Don't know if I forgot something. I didn't take into account that the changes of the time difference between local and GMT occur at the middle of the timezone.
