Therefore my correction factor should be 1 - [(9.7-11.7)/11.7] = 1.17

Done in US friendly units:
1 liters = 0.264172052 US gallons
Therefore: 11.70L = 3 US Gallons / 62.5 miles
Comes to 20.8mpg average (aggressive driving + ac always on)
Please report back to see how accurate this method is. I wonder if the correction factor is based on driving style....????
