Paul, you are welcome. See below a couple videos of wind flags on relatively calm days. You can see a lot of what goes on over 50 yards on a calm day. When you see those tails moving, there is enough wind that you will need to adjust your hold to compensate for the wind. How much you will need to hold off is determined by shooting your sighters and remembering those hold-offs as you progress thru your record targets.
You can see the times when the wind is really unsettled and those are the times not to shoot. When the flags are settled into one direction and are stable in direction and velocity, use your hold-off to predictably put the shot on target. When the air is unsettled, it's hard to predict where your shot will go. Avoid rapidly switching breezes for obvious reasons. Wind flags will show you when you need to hold-off and when you should shoot and when yo should just bide your time and wait. Doesn't it look like fun?
ps, in the second video you can see why the conventional wisdom is to avoid 12 and 6 o'clock breezes.
