I make all the intercept markings on the middle of the ocean. I select a position which indicates my position at the start of the plottin. The 0.00 mark. Then before I start making observations about my target I mark my second position (where I would be 3.15 minutes after) mark on the map using the speed charts. And the third position (6.30 mark) and fourth (9.45).
Now I can plot my course on the move. Ofcouse I could be going alot faster, but then my plotting wouldnt probably be as accurate.

I hope this clears up the method I use. Not sure I can explain it in anymore detail than this :hmm:

Sure I can try if you have any questions

Ok yes, I think I get a clear view of your method now, This means that you can for example follow a parallel course with your target and keep up (more or less) with it (and possibly revealing your position to escorts) cool feature. It's obvious that if you make 3 calculations, it's possible to get an accurate average by adding them all up and dividing that number by 3, thus getting even more accurate.

My method above uses the same rule: you don't need the Nil point that was provided on the 1500 m Bearing overlay from Pato or Redwine. You just need to be able to mark a spot on the map and use the charts and measure distances accurately using the PRR.
Will try your method from now on.

Thanks for pointing my in the right direction
