You're obviously not familiar with "auditing" or "computer bugs". Go-a-head, put your life in the trust of a computer. Do you know what "once bitten, twice shy" means?
WOW man, but that's a sorta demeaning to my statement. Please watch your words.Are you asserting that using a pencil and paper is somehow more accurate than using a hand calculator or a computer?Hand calc is the only accurate way I know I can "trust". Simple math!

Data is used by computers to do math, or estimate. If one is not right, nothing is right.The problem with Subaru's fuel mileage display isn't a computer problem, it's a data problem. It isn't an error in the calculations, it's uncertainty in the fuel delivery data input to those calculations, which is based on the long-term sum of fuel injector ON-time pulse widths. Consider that: 1) the fuel delivery per fuel injector pulse is measured in microliters, 2) fuel delivery vs. injector ON pulse width is a nonlinear function, 3) each fuel injector has its own slight variation in flow rate, and 4) there is some interaction among injectors sharing a common fuel rail that affects flow rates.All a computer CAN DO is "estimate".
EXACTLY ......what I said!
It's an estimate! (K.I.S.S.)
