Rated, Estimated Range and Practical Range with the custom period

EV is using the energy for driving and utilities (heating/cooling, sentry mode, ...),

I know the estimated range will be calculated with the recent driving report,

How about include the actual usage of energy instead just driving only ?

I want to say, practical range.

and, make people set the period also (last 10 drives, last 3 months, .......),

I feel, it will show more reasonable range to show ?

example, I have used 600kWh for the last 3 months, and drive for 2400 miles.

Just an suggestion...
