On a normal flight "switch off electronics while landing" happens once. If you think otherwise you have failed at flying (sorry, couldn't resist re-using your phrase there).

I read 'your six hour flight' and thought of a single flight. I didn't read 'series of flights' - that's where I slipped up. I failed at reading.
