2 Guys who where in my group shoot from the green and they both missed the target low.
I think it was target #14

I was there when the target was protested and as far as I know no one went and measured it but a few other shooters complained about the distance.

I think they just made a call to withdraw everyones score on that target who shot from the green stake.

I can see where confusion would come from if people started scoring their cards at #1 even if they started the shoot on target #11.
