Also you don't need a perfect 90 degrees AOB. Just enough so that you can see both the bow and aft edge.

But make sure you are not moving when the periscope is looking to your beam/side.

Sorry but with the value 1.94 the result fails. Although not relevant to the game.
The correct value is 1.85 for passing knots,

Needless your comment as my explanation is for 2 sockets
