maybe we need color coded double pins
bronze for staggered doubles
silver for true doubles
and gold for scotch doubles (not the liquid kind)
never worried about them myself - a flock of ducks don;t seem to count, you can triple on decoyed duck with a pump or auto.
I have had doubles on woodcock, in all the years, I've had only one absolutely true chance at a double on Ruffed Grouse flushed at exactly the same time , the right was the first bird I killed over that setter's points, I was so intent on marking it down in case he did not retrieve ( no worry, he did that one and every one after it) that the left barrel was more of a salute than a shot at the bird.
might be neat to brag about but outside a flock of waterfowl, or a covey flush of quail (still need to try that) where there are multiple targets, its a matter of luck of the draw as much as shooting skill. I find the vast majority of my upland birds, if paired on the ground, flush as individuals - often the second comes up at the shot.
but - if it matters to you - go for it - it gives you something to shoot for
