Whenever our students say they have trouble with long crossing targets, we ask them to show us their move on a 25 yard crosser. They typically hit 6 or 7 out of 10. How can one expect to break any kind of long target consistently if one cannot shoot a close simple one every time?
In Golf there is the 60/60 rule. That is: 60% of the shots happen within 60 yards of the hole. The Professionals work on their short game while amateurs practice the long shots. In Sporting there is the 70/28 rule. 70% of the targets are presented within 28 yards of the shooter. Shooting a 10 out of 10 on the close ones goes a long way to helping one become more consistent on the longer targets. The game is won or lost on the short targets not the long ones. If you kill All of the targets within 28 yards and 1/2 of the rest--your score is an 85! After all, its our experience, that most "40 yard crossers" are actually broken at 28 yards.
