When tracking targets at long range, 5 minute intervals aren't usually long enough to show any significant bearing changes. Could you take bearing readings at say, 20 minutes, and then as time goes by and the bearing changes become greater, go down to 15 . . . 10 . . . and finally 5 minute intervals? As long as I enter the appropriate times for each bearing mark, Mobo won't care if I tracked the target at irregular intervals?
If that won't work what do you do for tracking long range targets where there's very little bearing change using 5 minute intervals? Do you just wait for the target to get closer before you begin to plot bearings for TMA analysis?
