One way to measure the level of competition in a championship is to divide the points earned by the runner-up by the champion’s points. Expressed as a percentage, this quantity is between 0 and 100. Measured by it, ADAC Formula 4 was the most competitive championship in 2020, while Formula 1 was the least competitive.
Omitted: a few series I don’t bother reading about
Consider that FR Americas uses the same scoring system as F1, and its season also had 17 races. Lundqvist won 15 out of 17 (finishing P2 and P6 in the other two), and even that championship was closer than F1.
The last ever season of Eurocup ended with Martins as champion and a neat graph of 1-2 finishes. One can point to the Martins-Collets battle as evidence of championship drama, but it was mostly a snoozer with few notable position changes after the first lap.
Biggest disappointment: Paul Aron. One P2 and far too many unforced errors.
CryptoTower Racing won 16 out of 18 races… divided 11:5 between Ye and Dunner. But if one puts aside the four races that Dunner missed because of schedule clashes, the win counts are nearly even, 7:5. This is a championship fight that could have been but wasn’t.
The Edgar-Crawford fight was intense and entertainting, but overall the season was a disappointment by comparison with 2019. Prema team dropped out after two rounds, Pizzi (VAR) left one round later, and US Racing fell far short of replicating the strength of their 2019 lineup. The contest between Edgar and Crawford largely came down to who got torpedoed more often (Crawford, as it seemed to me).
