You make some good points, Joe.
Stage 3 is the one that will make or break ya. It's a set of 4 strings shot from 20 yards, and it's basically a timed bullseye event. Take your time and get your hits.
The other spots where people lose a lot are the head shots on Stage One. You'll basically do 3 Mozambique drills at 7 yards; shoot to your capability and don't get caught up in the need to go as fast as the Master Class shooters (If they're good you won't even hear a break for the head shot--boom, boom, boom). There is a 2x head shot portion in Stage one--again, don't rush.
Joe is right, it's easy to score well. If a lunkhead like me can make Master, anybody can do it.
