Bro today i will upload few pics of the average meter of honda city....thers some information about it which members might not know yet. When u press the button repeatedly to bring the average screen there isnt one window of info which u get on that screen. There are 2. The top is a left right scroll bar type thing n the bottom is a digit figure.
The top bar that scrolls left right is an ACTIVE display which keeps on changing immediately if u increase decrese the rpms or speeds to give the most accurate current display of the average the car is experiencing with current driving conditions and throttle application.
The bottom digit figure shows u a predicted average which u will get in case the current driving style is continued for the whole duration of the remaining fuel in the tank. This figure can keep on deteriorating or otherwise slowly and gradually and this is calculated by the car looking at averaging out the data from last ZERO till current time. Last zero means when u zeroed the meter last time after the refill maybe.
This is what i have observed it to be, expert opinions are requested because this is just my observation and not company verified data.
