I've been experimenting with a spreadsheet that uses the Ekelund ranging formula and time correction give me an estimate of target range. Unfortunately, there's a big problem. Because DW only returns bearing measurments to the nearest degree, it introduces a significant amount of error into the formula, which already depends upon idealizations to begin with, so it frequently gives answers that are radically wrong. It's like... "no way... he can't be 145yds away at the turn, I'd have hit him!"

I was wondering if anyone else had experimented with this idea, and if they had any techniques for minimizing errors, or if they felt the technique was just unsalvagable?
