Digital and Analog Gas Gauge Accuracy Issues

[Buddaboyle]

So I was driving my car back from work yesterday and when I arrived home my analog gauge read just over a 1/4 tank with about 150km range left on the digital readout. When I started my car this morning, to my surprise, my analog gauge read just over an 1/8 tank and said I only had about 80km range on the digital. Now it was colder the next morning, but not by much in comparison to the day before (0 degrees Celsius the day before to about -3 the next morning). Then on my drive to work which is approximately 20km, after I parked it read I still had 78km range which is only a 2km drop in range after a 20km drive?? I find this extremely odd, has anyone ever encountered something like this? 2019 G70 3.3T Sport

I am going to guess that you were not parked very level.
