I think the difference here is constant failures vs occasional failures. They are two different things.
The first would be the deal breaker, the other, just normal stuff. If your shooting enough, youre going to see the occasional stoppages, for whatever reason, and if youre not seeing them, then you should be setting them up.
Shooting regularly in practice isnt just about accuracy. Its about knowing your gun and what to do when things might go wrong. Thats the time to figure things out, and those sorts of things should be regularly practiced as well.
If and when they happen, you want to be at the point in your skill set of instantly executing the malfunction drill and continuing on. You dont want to be that guy standing there, mouth agape, staring at the gun with a stupid look on your face thinking ***?
