In a similar situation under similar stress I would hope to do half as well. Range time cannot prepare you for the adrenaline surge total terror your life is on the line situation this woman faced. There is no way to practice for that. It’s hard to hit a target when you are breathing 40 times a minute with hands violently shaking. I say good for her!!!
Your words are true. It’s estimated that accuracy deteriorates about 50% in a real life crisis. Putting it in bowling terms, it’s unfortunate she didn’t “pick up the spare.”
As a trainer for military police including prison response teams, I cant disagree with you more. There is a thing called muscle memory. During times of stress is is common to loose fine motor control - true. But time on the range practicing drawing, firing, clearing failures, etc does help. And a LOT of time helps a LOT. Train with stress inducing activities, and it can help a lot more.
