I usually try to be at 0 knots when I start plotting so I don't have to worry about my own movements messing up my calculations! Not always possible of course and I too had never thought of simply using the 3.15 rule to make it much easier.

I do find the nomograph very helpful for quickly working out speed etc and distances covered in real nav.
