The longer you're on a leg, the more likely you are to get a 'good' bearing rate (although longer intervals of data also decrease the accuracy of your RHek. There has to be a balance...grr.)

One question though...Are you calculating T* (time of the range)? That could be your problem too. Maybe he was 145 yds 25 minutes ago and you're trying to apply it for time now.

Yeah... I get both the range at the turn and the best range time. I guess that's my other problem, I've been trying to do it like in the text books, and only use a few bearings. To do it very quickly. I guess I need to work more slowly.
