I guess one of the points of the question is whether the bar to being able to sit and start racing has been increased.
But as a friend told me last year. Cat 4s are Cat 4s, no matter where they are, no matter what race. This was in reference to question whether a C race win at a certain crit was more prestigious than another crit (both weeknight crits).
I see very little in the way of team tactics in the weeknight crits I do in the C race. B race is an entirely different story, and it's the reason I joined another team this year. I wanted to be on a team that showed up to the crit that I do the most. Rather than race alone or with just one teammate.
Cat 4s have always been Cat 4s.
So when I become a Cat 3 is there a new hidden subforum that I get to join?
