Consistency.

Without consistency, it's nothing more than a one-time circus trick. 10 yd Carbine Bills are a good test of raw speed, vision, connection, and recoil management, but they don't expose flaws in your fundamentals the way distance does. Walk out to 30 yds and start shooting aggressively to see where your skill set truly lives. 30 yds exposes problems and amplifies weaknesses with your fundamentals. With your vision, mount, and connection. It exposes whether you are able to shoot consistently and be confident in your on demand performance. It shows you where you need work. That doesn't mean the plateau inducing "slow down to get your hits" answer. Address the actual problem and fix it.
