NO! That is not at all what any of those people said.

OK. Maybe I got it wrong.
Darn right you did.

Still, some people claim 19.5 miles per gallon, which I posit is an
impossible level of precision given the tripmeter/pumpmeter method, even
when taken over 10 tank fills.
Bull crap

Most tripmeters don't even have a decimal place, so, you can't include
decimal points in the calculation.
Bull crap

Worse, the fill-level estimation is crude at best, where again, there is no
decimal point.
Bull crap

It's a mathematical fact that if your measurements don't have decimal
points in them, then your answer can't have them either.
So? Both can and do.

Anyone quoting MPG with a decimal point has to first get those decimal
points into the measurements!
