Fantastic explanation RR
On this piece I wanted to add a small comment:
Quote:
you can alter your course to about 110º from the target track instead of 90º. This will reduce your gyro angles in all reasonable circumstances to less than 5º. I'm not going to worry about it myself.

The manual for the Attack Course finder uses an example to illustrate how it works and do you know what track angle is chosen? Bingo .... 110º
I quote the manual:
Quote:
5. EXAMPLE: Heading by compass 230 degrees. Enemy relative bearing by periscope 315 degrees. Angle on the enemy's port bow 25 degrees. Estimated range 5000 yards. Desired track angle 110°.

Good proof of how right you got it
