I would go along with what razark said. I use multiples of 3 min. as this is convienent. That is 6 or 9 min. intervals when the target is distant or you have plenty of time, and 3 min. when the target is close and you intent to shoot soon. The clock button inaccuracy is a known issue; I never use it anymore. The visual plot is, as you found out, is subject to error. It was the same way in real life. I would think in terms of half a dozen to a dozen points for a plot. IMO, you can't expect a good level of accuracy, from 2 or 3. Really, a good plot is part art, and part science. It is also desirable to be able to make visual estimations of the AoB, and not rely entirely on stadimeter ranges for your plot.

I also enter everything into the TDC, and check to see how well the data matches with observations. If you've got a good idea of his course, that can help you refine the target's speed. I don't know what mods you might be running, but I love the 3D TDC mod for this.

Agree with this 100%. This, I believe, is one of the things that made the TDC such a powerful tool.
