Ah, bummer! How did the bike come out? Your analysis sounds spot on. I would only add that I have heard this desire to go to blue to avoid erratic riders in yellow a few times this weekend. It is not correct thinking. A quick, but inexperienced rider is more dangerous in Blue than in yellow. Stick with the appropriate level. You need to learn to pass safely, and you're not going to do that riding above level. It takes years to learn to be a good track rider. Give it the time it deserves. Pay your dues in the appropriate group. There's a lot to be learned by riding with those "throttle jockeys".
And sorry we never met up! I didn't get my title for the sprinter, so I wasn't able to bring it.
