If you shot the stands numerically then you suffer a bit with the same malaise as me - in that I always shoot the first half better than the second half. If I could shoot second half as well as the first I'd end up with a half decent score, but the wheels always come loose and ruin the card for me (for C any way).
Not sure whether this is fatigue or lack of concentration or what it is. I haven't done many 100 ESP but one I shot I hit 38 in the first 50 so I thought this is looking all right, and then hit 14 in the next, and it wasn't like I'd done the easy 50 first and then done the hard 50 it was just me.
Superb review by the way with a good variety of targets, although what happened to stand 9?
