Thanks so much to ASH556 for taking the time to write up his experience with the class, and thanks to everyone for their comments.
This was a really strong class. I am very pleased to have awarded six Light Pins and seven Dark Pins. All the pins require significantly more than a base level of competency to earn. There are a whole lot of people who have been shooting and training a long time, who are perfectly competent and frankly would probably get the job done in a great many situations, who would not get any of the awards. Dark is hard, Light is harder, and Turbo is intended to ballpark M/GM-level drawing and shooting on a single target.
Performance loss in a stressful on-demand circumstance such as the class testing, compared with the level of performance one experiences in a practice environment, is totally normal IMHO. It's definitely the way it works for me.
