I understand and considered it, but I am shooting for that degree of precision. a 100th of a gallon is a noticable amount (about 1/6 of a cup), at least it is noticable at the high end of the mpg spectrum. I could go a whole mile on that
. Also, there are many vss tics in a 10th of a mile (way more than 10), so I think the data environment supports at least 2 digits after the decimal point.
Besides, I don't know what else to put in the space at the moment
I'll be posting the source shortly.
