Racing fuel you run lean to stay consistant and alcohol you run fat to stay consistant.
The reason alcohol stays consistant as the air gets better is because most of the time as the air gets better the humidity goes up at the same time. Alcohol doesn't like humidity, so eventhough the air is better, the humidity is up, makes it a wash. Therefore ET stays the same.
