Oh yeah, but here's the thing that REALLY gets me. Your grandpa was doing the math in his head and then just deciding "eh, close enough" which is basically what everyone does anyway. I remember watching people at the bar tab who would meticulously calculate 18% to the penny, then round DOWN to the nearest dollar to avoid the extra 40 cents. Like wow, way to show your waiter you're a real math wizard. The whole point of tipping is that it's supposed to feel like a THANK YOU, not a tax you're trying to minimize. Your grandpa rounding up probably made that server's day better than someone who left 22% but acted like they were doing you a favor by explaining exactly how they arrived at that number. Honestly, I think the old school way of just picking a number that feels right says more about your character than any percentage ever could.

Precinct 7 has like 80k residents, so did the decimal slip change the actual number of incidents from roughly 1,000 down to 100, or was it the rate per 100k that got inflated for the whole city map?
