I do like the option of shooting 10 or 20 whatever you have time for. My only suggestion is if the same group is staying together to shooti 20 straight it should be an option to stop only once per 20 targets to do the official score recording. Signing all the cards and getting with the official scorers at the little hut took about 15 to 20 mintues per 10 target range. So for 20 targets it was 30 to 40 minutes. On the F&G ranges we did not stop between ranges and it sped things up a ton.
