Senior Max has 37 in the Final, but that is after the field is trimmed down. They started with 70+ and had to qualify through the Heats to make the finals. Same is true for Junior Max. Master Max hasn’t had enough entrants to require the trimming before finals, so all Master Max drivers make the show.
Not true. I was there. Only 37 Seniors. They were divided to 4 groups and each pair was 18/19 drivers in 3 heats for each group. This is not changing total.
