Question Fuel Mileage Check

[JJT-NC]

My 2022 DS is getting between 6 and 7 with 4,000 miles on it so far. I’ve been on flat land for the most part but it seems I am more likely to see 7 with modified foot behavior. ;-). Need to break in the engine and my foot.

But, my trip computer only reports mpg to the whole number, such as “6.0”. Am I missing a setting somewhere or is this how it is supposed to work?

I should have also mentioned that I've been towing a 6,100 lb GVWR Wrangler Rubicon for all those miles.
