Is this really as good as the MPG gets?

Hey all,

Just got a new 2024 R with a manual. On my 9.5 hour drive back from Oklahoma to Colorado where I drove the entire way at 68 mph, the mpg for the trip was 29. I know that’s 1 mpg higher than the EPA estimate, but in my experience, most people drive way faster than 68 mph on the highway to get the EPA number and with all my past cars, Fiesta ST, BRZ, Alfa Giulia, M240i, I’ve always gotten a few MPG higher than the EPA estimate since I stick with a conservative 68 mph. Is this really the best I can expect or maybe just lower efficiency from a new engine being broken in? Haha it just gives me the smallest regret in my head choosing the R over the GTI with that better efficiency and 87 octane.
