Not sure if everyone knows, but Hexta shoot results also gives a group size in terms of a 'Berdan String'. Well, HEXTA actually reports the average size of a Berdan String. This sums EACH SHOT'S actual distance from the centre - not simply the worst few as in our unfortunately flawed scoring system when high numbers of Xs and Vs are involved. The standard of accuracy has increased so much that, at the top level, targets have not kept pace.

Peter,
When ETs are good enough and importantly affordable enough to become the only type of target in use, then I agree that a more precise way of rewarding accuracy would be good. How about SD of MOA from the centre of the target? For the benefit of spectators, the SD would need to be updated and displayed on screens after each shot.
It would make for some interesting changes to strategy e.g. deciding whether to keep sighters .
