There is also that matter of height, and left to right placement. At 200 I like my last flag to be as high as is legal, with the pivot centered on the target. I want the next farthest to be in line with the first (on a line from target to rifle) and at a height so that it is stacked just under it in my scope ( with a 36x) Higher power scopes, without a raised horizontal crosshair may not have the field of view for this arrangement. Closer flags, that are not to be viewed from the scope are offset to the side of the bench where I am sitting as far as I can without getting in the way of the shooter at the bench next to me, to make them easier to see with my off eye, while behind the scope.
At a match, shooters who are experienced on that range will modify their distances based on experience. At Visalia for instance, the nearest flags are usually well under 25 yards, which ever flag is nearest the distance that the western berm jogs to a lower height should be just past the drop down. Also, on the left there is a driveway past the end of the range cover that forms a chute for a 6:00 wind and making the conditions next to it have different conditions than the rest of the range where the wind is more blocked ,because the range is well below the grade of the surrounding land. At the eastern most bench, the prevailing wind (NNW) does not go all the way into the "corner" beside the tall, almost vertical side berm, but leaves a sort of eddy pocket that may have significantly easier conditions.
These are just a few considerations that effect flag placement on one range. I have also been lucky enough to have a shooter better than I (long list) share with me what flags he was paying the most attention to in the day's prevailing condition.
