Are the scrutineers picking on my driver? - Update after the Italian Grand Prix

The scrutineering data for the Italian Grand Prix is straightforward. Somehow, despite being the first car out, Leclerc isn't the least tested. 

The χ² for the race is 1.38, so any differences aren't statistically significant. 

For the season to date, it looks like this:  

The "tested less than expected" cars are definitely further from expected than the "over-tested" cars. I think that's because the Aston Martin and Cadillac teams have remained what we will politely call "not good", while the rest of the teams have come closer together in terms of results. 

The χ² for the season up to the end of the Italian Grand Prix is 4.32 so any differences aren't statistically significant, but the number is still increasing.
