I do have a funny ass story about the theory.
Sighting in muzzleloaders, my buddies are the guys to buy new shit and set it up, I dunno, say half our before the hunt. He goes to sight in his new muzzleloader with a scope from another rifle from someplace like Walmart. It was dialed to about 4” from center at 50 yards. He says that’s good enough, another friend says just shoot “one more time”, adjust the scope and have at it. He adjusts the scope, then my other buddy says you gotta tap on the scope to set it. So he does, he brings the rifle up and the crosshairs now make an “x” in the lower left corner of the view box hahahaha. Tap on it
