I did a steel challenge today for 200+ rounds. No issues at all regarding functional reliability.
I also watched the video, and tried to induce a striker release by (with an unloaded gun of course) cocking the gun, then smacking the base of the grip on the ground to try and get the sear to slip enough to release the striker.
It did not fail, but even if it had the firing pin stop would have stopped it. To counter argue the video, well if I was pressing the trigger a little there is that "chance", but that's not a fair safety test to be pressing the trigger while trying to slam base of the grip because I would simply "pull" the trigger while smacking the gun. So the ND would be caused by having a finger on the trigger.

Now, what I'm never going to do is simply shoot the gun, never clean it until it fails and get a round count as an evaluation. That's kind of lame. I just won my division today in production steel challenge because a much better shooter than me totally botch the first stage with malfunction after malfunction after malfunction.
It's a competition trigger, and I suspect here is not one professional competitor out there in any sport that doesn't go into an event without having made sure his equipment is ready as it can be.
So my main question is, when a Timney trigger fails, is it something that could have been avoided by simply cleaning the gun, which should be frequently done anyway.
