I have absolutely no idea how much I pay for water, but vaguely think it’s probably between 0 and 100. Why does knowing it’s small mean you can predict it precisely, in a world where auto-payment exists so you never have to actually look at your bills?

I mean that it’d be extremely unlikely for me to not be able to predict my water bill to within ‘tens of dollars’, because that is the entire amount.

Also, I get receipts by postal mail even if I auto pay them, so I guess that makes it easier.

My water bill is $200/quarter.
