I also think there is something incorrect about those chronometer shiplength scales.

1 knot =1.852 km/hour ("." means decimal)

so 1 knot= 1.852 *1000(meter)/3600(seconds)= 0.5144... m/s ("..." means repeating fraction)

Thus (for the yellow scale), if 100m takes X seconds @ 3 knots you get the following equation:

100(m)/x(seconds) = 3(knots)*0.5144...m/s= 1.5433...m/s, then x=100/1.5433...=64.79 seconds (stopwatch shows about 62)

So the yellow scale is about 3 seconds short.

For the red scale: 150(m)/x(seconds)=4(knots)*0.5144...=2.0577...(m/s) ; x=150/2.0577...= 72.89seconds (stopwatch shows about 68, 5 seconds short)

For the blue scale: 200(m)/x(seconds)=5(knots)*0.5144...=2.5722...(m/s) ; x=200/2.5722...= 77.75 seconds (stopwatch shows about 74, 4 seconds short)

It may not be much (5-7%), but it is not anything like german manufacturing precision.



Another issue that needs mentioning is AOB. In the thread of the other mod that uses this Ujagd mod Onelifecrissis said the following:

When measuring target speed with the U-Jagd chrono it doesn't matter whether the target is moving towards or away from you, and it doesn't matter what their AOB is. All that matters is that you're moving as slow as possible, preferably with the target straight (more or less) ahead of you.

This is true in principle. However a small AOB may hide the true stern behind the side of the ship's hull and makes measurements somewhat difficult to time precisely. An 90 degrees AOB view gives the best accuracy as the ship is rendered with the maximum amount of pixels wide. However you need to make due with what the situation provides. It's just something to take into consideration.
