I saw a 30 second segment in something I'm sure was about F1 engines that had something on a dyno and they flipped (while running) from the engine map to an ai predicting the engine timing per-firing and you could hear the thing smooth right out.

So no I imagine there's actually quite a lot of wiggle room to be off. Less so if you want it to last a million miles. But 30k?

Well, yeah on top of one in billion chance of bitflip you'd also have one in million chance that the bitflip would cause it doing something incorrectably wrong.

There is a lot of protection in modern engine, like retarding timing when there is a knock or long/short fuel trims to correct for any changes in the sensors.
