Good point on baseball, because every plate umpire has a slightly different strike zone.
When I was a kid we used to argue all the time about sports stuff. We had a rule where you struck out if you took 3 swings & missed. No walks.
One day I propped a garbage can against a backstop and we said if it goes inside the garbage can, it’s a strike. Outside, it’s a ball. We called it ‘garbage ball’.
It was amazing how many times I got on base after that.
