What does this mean, exactly?
Obviously, USPSA classifiers involve core shooting skills and gun handling skills, but since they are repeatable, we can use a desired performance score on a classifier to work backwards and establish aggressive par times that guide a competitor's training. Over the long run, practicing these core skills helps consistent match performance.
I'm challenging you to come with a goal in mind: if you want to get a class bump, let's work backwards to find out an aggressive par time that'll get you there!
