To get DG you must have 13 points or less. I finished with 14...
Yes we discussed peaks and valleys alot during our 4 days. In fact my uncle who can shoot very well, didnt even make graduate this year, and last year only missed by 2 points or so.. He was definitely in a valley to say the least.
BTW you can take a 2 day weekend or weekday skill builder and take the test again... I plan on doing that to get my DG. But until the rest of my group I normally go with gets DG we will be doing the Shotgun and Rifle classes =)
