And, if we're at the "stabilized" 100,000 sample calculation, all we're doing is multiplying by 100,000, adding zero and then dividing by 100,001 each second. Doesn't look to me like much would change.

After 30 seconds of zero mpg at a stoplight, and assuming a "stabilized" Avg Econ reading of 15.5, the equation is: 15.5 x 100000 / 100030 = 15.49535, which "rounded" is still 15.5. And I still get 15.49071 after 60 seconds. After 2 minutes, it's 15.48142, which is still "15.5". At this rate, looks to me like we could sit for at least 5 minutes, before we'd see 15.4.

Maybe the Mad Doctor will enlighten us when he returns.
