"I don’t have any hard and fast rules. It depends on the class, the other students, and whether I think I can remediate the student’s problems without slowing down the rest of the class.Whether you are an instructor yourself (and I'm not) or just a frequent student, it's worth a read.
It also depends on the violation. Someone who has good muzzle discipline but is unintentionally putting his finger into the trigger guard too early is a very different problem than someone who is casually muzzling me or the other students."
I like that he draws the distinction between someone who is unsafe due to fatigue or medical reasons and someone who is having a hard time with following the safety rules.
If you're a student, I think it's kinda incumbent on you to also keep an eye on your own performance. I've pulled myself off the line a couple times when I noticed that I'd reached a level of fatigue or dehydration that was reducing my ability to focus enough to cause me concern.
