Do you have testing data that shows pumps are better than that?

Not just what it takes to pass ... which varies state to state ... some hold to less than 1% +/- and inspect every year ... others are not nearly as strict.

But also the rate of failing those tests ... pumps failing to pass inspection is not all that rare ... more in some places than others.

What method do you use to determine 5% ? ... what level of accuracy / significant figures , did you have for the distance measurement and the volume of fuel measurement ?
