Ok here is my manner of calculating the speed.
Once i have read it on the ubiforum. Since then i use it always.

- Recogn the target.
- Set the crosshair at the beginning of the target.
- set on the stopwatch
- set it off when the crosshair is at the end of the target.
- take a look in you recognbook how long your target is.
- Calculate: time divided by the metres of the ship multiply the outcome with 0,1942.

Now you have the speed.

So for example a ship of 90 metres with a time of 30 secs

30 : 90 = 0,33 x 0,1942 - 0,06. So the speed of the ship is 6 knots.

For me this works great above all named manners.
