Scrutineering at the Hungarian Grand Prix:
The difference from expected is lower than at the Belgian Grand Prix, with an χ² of 1.22. That's because of the number of cars that were tested as much as expected, 10 out of the 22.
The three cars least tested compared to expected were the three cars that didn't finish, those of Perez, Bottas and Piastri.
While Gasly was the most over-tested compared to expected, Hulkenberg gets to celebrate his first points of the season by having the third-highest number of tests relative to expectation.
The season to date:
Even though it doesn't come close to being significant, despite the increasing number of events, the χ² is increasing and is now up to 3.76.
Even though it doesn't come close to being significant, despite the increasing number of events, the χ² is increasing and is now up to 3.76. The top four most over tested are Norris, Bortoleto, Hamilton and Russell. Bortoleto still stands out in that crowd. I know it's probably still the effect of relatively small numbers, but he's not up there based on performance or number of finishes; other drivers have finished more races and still aren't as high up as he is.
Stroll, Bottas and Perez are the drivers least tested compared to expected and are the bottom three in the championship.
There is a relationship between not finishing and not being tested, because some tests are only performed on the cars that finish. The car starting to work moved Norris and Piastri out of the bottom and it will be interesting to see if Aston Martin's improvements do the same for Stroll and Alonso.
No drivers have been tested exactly as much as expected but Gasly and Piastri come close on +0.053 and - 0.053 respectively.
At the halfway point of the season we have an increasing χ² value, some movement at the bottom as the cars become more reliable and Bortoleto being over-tested compared to his results (even if the difference isn't statistically significant).
