In the past when unforseen things happened like target changes due to weather or other things, we scratch this target from all cards and base the results on the remaining number of targets. It isn't a favorite for those who shot a ten, but it keeps the field fair for everyone not just the shooters who had the open lane and the ones who shot after when it was covered.

But the first shooter who came to this target and found the scoring rings obstructed should have put the call out for an offical of the club to come and rectify the situation. It is in the shooters right and is in the IBO rule book. Not to mention in this situation it would have given you a real good idea which group did it.
