This was triggered by Keith's Vane-question.    

What about wind-indictor placement in terms of height above the surface level.   I see (on the EG range) indicators placed at everything from a couple feet to a couple yards or more above the grass.   some of our best benchrest shooters use a relatively low windflag placement so maybe it is really a moot question and experience and learned skill is more important than how tall the "flag-staff" is.

My limited logic tells me that the theoretical optimum placement would be adjacent to the bullets trajectory; however much of our "condition-management" technique seems to be derived from modern benchrest competition.  If I am correct that is a much higher velocity (flatter trajectory) game played at shorter ranges so lower indicator heights would fit trajectory in the MBR game.

Please bear in mind that I am slowly transitioning to centerfire rifles from mostly shooting the 22 rf cartridges; and a 40+/- gr. bullets at 900-100 fps at 200 yards is a lot different than even our typical 32 cal bullets as used in competition.

I place mine just below my line of sight through the scope. They should be as close to the path of the bullet as you can see over.

Some shooting Venues have a height limit. In NBRSA matches the flags cannot be any higher than bench top level and the bottom card. A good rule and fair for all, I have shot next to a competitor with his flags five to six feet in the air and it does present quite a distraction. Its also best to watch the flags on both sides of your lane so you can see a change thats coming your way before it gets to you. If its holding in their lanes you won't get bit by a rapid change in yours.

Not a rule in ASSRA Terry they just can't intrude into another competitors lane. At our range with the benches almost touching each other and minimal room between the target frames the tails often times come real close to it. 
The ASSRA Rule book is in the announcement section and being a new competitor it is worth reading to familiarize yourself with rules. There might come a time when you want to protest a score and the guide lines for doing so and how its to be conducted are there as one example along with tie breakers, equipment  when is a bullet considered in or out as well as the entire list of the different matches offered most if not all are typically shot at Etna Green.
