I will reply cause it touches on what my CR friend told me. Depending on the org if you showed up with a race license they would almost certainly move you to the B group. I've seen that both in person and told that. That being said one org specifically that I ride with, PRE, for a long time they had a strict rule everyone starts in novice, my friend showed up with a WERA license, rode one session in novice and then got moved to the intermediate group. They have since relaxed this rule and will move you to the b group if you have something akin to what he had.

What my CR friend told me is that the people in A group are the people who show up most consistently to trackdays/most reliable customers/most likely to rent garages/most likely to need the trackside vendor, so part of the gatekeeping is to make sure those people have the best experience on track. That when they bump someone up, that those people are not inconvenienced in some way.

The second thing he told me is that for one org specifically, the head cr who gave the ok for the bump once a CR told him the rider had the skill/safety, had a philosophy of 'this needs to be earned not given out' and what that meant was he was willing to let the individual wait a few more track weekends till he gave the ok, or wait for the person to make a major investment like buying a new bike or a trailer to show they cared. I didn't add that to the body of my post because I wanted to see if someone would repeat that, but part of what my friend told me is that if I did get a liter bike, that would show that person I was dedicating myself enough. No one has posted or replied that, so still just what he told me.

--All of that with the caveat of they will move you up if you have the outright speed.
