Is there a readme for setting up guns ?

The convergence settings in the sim are in meters, 100 yards is roughly 90 meters.

For example if you wanted to set them up for 200 yards, the appropriate conversion would be to enter 180 in each of the convergence text boxes.

I keep horizontal and vertical convergence the same for maximum effect. Using different values would only be useful if you come up with some pattern harmonization technique (this is the same reason we can set up each gun individually).

In point harmonization all guns are boresighted for the same range. This gives maximum effect as long as the pilot is an accurate shot (can judge the correct range to fire at and knows his deflection shooting to land some hits).

In pattern harmonization, guns are boresighted in pairs and each pair is set up for a different range. This lessens the destructive impact of a well placed shot, but makes it easier for a less experienced pilot to at least score some hits over a wider range of distances.
