Vmodel: 107,9 kph
I think that the only way to fix this "problem" is to collect more data and
do more test.
50s:Here there aren't some data due the traffic that forced me to brake..
What about to consider the mode and not the average(statistic mean(?))?
I need to do again this test in a major proper way of course

You will be wasting your time unless you do a basic test of a change that
does alter drag - eg windows up / windows down - and ensure you can measure it. Chasing imaginary changes is no fun.
