Normal amount of misfires on N63B44U0 that can be tolerated

Howdy,
I've run noncontinuous monitoring tests through the Car Scanner via ELM 327, and it showed some 4 misfires on 5th cylinder in the idle run.



I remember having problems with engine shutters on N52B30U0, and back then it had done 100+ misfires weighted moving average in 10 cycles. That was a faulty ignition coil.

Dealer shop replaced some coil (didn't say on which cylinder), and I wonder if this replaced coil is causing misfires. But even if it does, are these 4 misfires in the idle warmup run OK?
Can this easily be tolerated?

I'm asking because I have a 11-year-old N46B20, and last time I checked it showed 0 misfires in the 10 cycle WMA run and 0 misfires in the current run on every single cylinder.

Thank you.

Swap coils to a different cylinder and see if it follows.
