Why Not Better MPG?

I’m driving a 2017 EX and I’m getting around 20 to 23 city and about 26 highway. That’s driving in the ECO mode. Drops well below that in any other mode.

2021 LX, ECO mode only. VERY easy on gas (tach never reaches 2k RPM) and use Cruise 90% of the time. 120 miles/day commute, only 20 of which is city, and I average 30-31mpg. 2500 miles already and this is only week 4 of ownership. Previously drove a 2018 Soul 1.6L with similar results.
