Some Are Subjective

Tactics, judgment, verbalization, awareness and some other skills can’t be scored with a timer or a ruler. But just because you can’t measure something with numbers doesn’t mean you can’t measure it. You might measure your tactics with after-action analysis of your video-taped performance. You won’t get a numerical score, but you’ll get accurate and useful feedback for improvement.

By all means work on your fast and accurate shooting. It’s foundational. But don’t get so caught up in it you push it past the point where developing other survival skills are ignored.
