You're right. Staying proficient with gear means using it for more than training. I do the same with a 13cf pony bottle which is why I know I can make a safe accent from 80' with it.
If someone is going to dive a piece of gear then they should use it frequently. That simple act of training will make a huge difference in an emergency.
