I play at 97% realism. The only concession I make is that I leave stabilized view on. I may consider taking that off at some point.

I don't use the OLC GUI. I use pen and paper, and physical slide rules and whiz wheels.

I did use a maneuvering board that I had printed out and laminated back when I was first learning manual targeting. I used dry-erase markers and a cheap plastic kids ruler, protractor, and triangles set.

It's actually scary how accurate you can be using improvised tools like that.
