Sunk my FIRST Destroyer!!!!!

Right, as previously stated here is a screenshot of how I have been using the nomograph to calculate targets speed....i haven't yet had any misses using this method, but I get the feeling that from what some people have been saying, my calcs could well indeed actually be off!!

The marks and points on the navmap is for reference only, i'm moving into a firing position on this fat convoy but no solution has been formed in anyway using the figures plotted in this screenie....so here I go:

1. Mark the 2 points on the map, wait the usual 3 minutes and measure the distance between them which in this case is only 0.4km.

2. I then look at the nomograph, start at the top of the knot scale, and drag a slant line down to 0.4 on the distance scale. The resulting reading gives a rough speed of about 3.5 knots or so, least that's how I interpret it. Notice I haven't done anything at all with the minutes scale on the nomograph.

Now, please tell me is this method right, close to being right, or totally wrong? I can't imagine it being totally wrong as i've been hitting targets successfully with this method thus far in this career. I'd appreciate feedback from the more experience Kaleuns in using the nomograph to see if I am right. Cheers guys
