How are you guys achieving such high average MPG?

My car is only averaging 20 mpg at best. I'm not doing only N driving, I typically use normal/some eco with some spirited N driving in between. I'm based in FL. I know this car isn't for those who are looking to save gas, I know what I was getting into, but I've seen people attain 30 mpg. How do you guys do it?
