My OBC shows: 9.7 L/100

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)
Okay, I'm not familiar with the metric system of gas consumption, but isn't 9L/100km equal to 26.13MPG. So if you calculated 20.8MPG, then isn't that a correction factor of 0.74?
