The Humbler Drill is an extremely taxing when performed from the standard 25 yard distance, but it is a great skill test.
The biggest issue I see with people shooting this drill is that they underestimate the time limit, and actually have a significant amount of time left over that could have been used to increase their score.
This drill was found on pistol-training.com and has been popularized by Larry Vickers. If you are ever in need of practice drills, pistol-training.com is a great resource!

The Humbler is the nickname for what is otherwise known as the 700 Point Aggregate. As of this writing, no one has ever claimed a perfect 700 on the drill.
The drill uses NRA B-8 bullseye targets at a range of 25 yards. A fresh target is used for each string to minimize scoring errors. Rounds impacting outside the marked scoring zones are zero points.
