I have shot a PPR once. While I enjoyed the challenge, I question its place in a match. I think it unfairly punishes a missed shot and lesser shooters. On paper targets, the consequence of a poor shot is discrete - fewer points or a Miss. On static steel, a missed shot results in a Miss or in taking a little more time to hit it the second (or third) time. But on the PPR, one bad shot could cause a death spiral. The shooter either spends loads of time trying to get the last couple plates or incurs two or more Misses. The consequences of that bad shot or shots gets magnified b/c the challenge becomes increasingly more difficult. Then, the difference b/t the best shooter and the worst on that stage is not reflective of the worst shooter maybe just missing one shot; it becomes an exponential difference.
