I left my Trip 2 untouched for 5 fill ups to keep an average against my logged miles/gallons. Both match *exactly* after 700 miles.

I reset Trip 1 MPG and Miles every fill up to get an idea of instant MPG, and it seems to average against a stored constant.

The first reading seems to be skewed toward the last reading before reset, then adjusts quickly up or down based on real time driving.
