I figure that if I don’t do a quick mag check at the end of the flight taxiing in or just before shutdown, then if something was wrong, it may spoil my day the next time I decide to go flying and I discover it on the next start-up.
I am always weary as I once had a plug lead come loose in flight and if you didn’t do a mag check before the hot take-off, you’d be running with less redundancy and the associated risk over a heavily populated area on takeoff.
