Obtaining accurate speed estimates from map plots

So unless I'm firing from close proximity, I don't have very good hit percentages. Now when I use map tools to plot stuff, there's a margin of error there too, which doesn't affect the course so much as the differences in range throws the speed calculations way off. Is there any way to obtain accurate speed estimates?

I use this formula .. lenght of the ship / sec on the clock X 1.9 = speed of the target ship . However the stock book does not have data about the lenght of the ship . So I have been asking for information if there is a Mod that has better data in sh4 .. I play sh5 and The SOAN book has this contained in the recon, book
