>That's likely to be the exact reason why the reliability specs don't line up with reality: your test jigs are almost certainly going to be inserting the plugs directly with exact precision, whereas in practice people are going to just "jam it in" and apply significant side-loads as well as misalignment and levering forces.

as someone who was involved with endurance/reliability testing of other physical products, I think you'd be surprised.

Randomized jitter and movement patterns are often replicated and considered.

I agree with the parent's comment. I also worked with automated test setups and did human tests. Nothing compares to a human tester. We tested small remote controlls and it was amazing to see that a human hand can inflict more damage to the product that an automated test setup. (the remote was given to different persons just to push the buttons until we reached the desired number of button presses).
