ICE mode efficiency

Driving my 2017 for the first time on a long trip requiring gasoline I wondered if I wanted to get the most mpg out of my gasoline should I be in normal mode or hold. I realize hold is normally used to save battery for city driving later but if that is not a constraint which mode gives best use of gasoline at highway speeds and why?

For longer trips, I switch to Hold once up to speed on the highway and retain battery for use in potential stop/go traffic. Once within range of my destination, I go back to Normal. Driving this way, I have averaged just over 45MPG on the ICE for the life of the vehicle.
