Understanding MPG computations
It's been almost two months of Insight ownership for me and I feel like I'm still learning how the Insight works. Today as I was driving to work it occurred to me that when I reset, say, the segment read-out, I feel like the mpg reads higher and changes often. However, the Trip A/B read-out, which is not reset and shows cummulative miles, has small incremental MPG changes. Today I decided to view Trip B, which I didn't reset and had about 70 cummulative miles from five separate trips. The mpg stayed at a constant 53.x mpg (city driving, CVT). Normally when I do a reset of the segment, the mpg will read a bit higher at the end of the trip.
Btw, when starting the car at --mpg, the sequence seems to be: 6.7, 25.1, 39, 41, 53, 54.2, 56.1, 59, 61, 65, etc.
It seems there are big jumps eary on and then the changes become more linear until it remains steady with small changes.
