oh bloody 'ell.
Let me think about this "out-loud"
My calculated commute each way is about 15 miles.
Filled my tank Monday afternoon, Odometer reads 49945
drove car home Monday - 15 miles (15 est. total)
drove car to work tuesday, home tuesday - 30 miles (45 est. total)
drove car to work wednesday, home wednesday - 30 miles (75 est. total)
drove car to work thursday, home thursday - 30 miles (105 est. total
drove car to work friday, home friday - 30 miles (135 est. total)
Odometer now reads 50057
50057
-49945
=112 odometer miles
vs. 135 estimated miles
112/135= 0.8296...close to my estimate at 100/120 miles.
But...
135/112= 1.205
Ah, that's pretty close and based on an imperfect estimate, I think I performed the calculation in reverse.
If the mechanical error is more like 1.05, then my "estimated" commute is a bit off and my real distance traveled is 112*1.05 = 117.6 miles and my daily commute is closer to 13 miles (117.6/9 one-way trips). That is possible. Until I break out a GPS, I can't say for sure.
It does not bode well for my mileage however, which would be less since I'm traveling a shorter distance with the same fuel consumption...
I'll post when I fill up next...
