Meat,
I totally agree with you on the consistency thing and a rider being predicitable. If a rider makes a sudden move like you mentioned coming right to the outside on the exit of a turn I agree he doesn't belong in I, if that move was sudden and wasn't a smooth one. That was the point of my last sentence in the original post above. If the rider signing up is consistent with his/her lines, runs good lines, is predictable and doesn't make sudden line changes like you mentioned, they probably do belong in I and should probably start there.
Hey, I do want to make one thing clear. Even though I was sometimes frustrated in B for the first 3 non Sills Enhancement days with NESBA, I still had a great time. The other thing I felt is that the sessions were very safely run. I didn't necessarily feel that way with the first group I rode with on the track. The other thing I want to make clear is the folks in the B group going a bit slower fully deserve to be there! They are having a great time as well. I also believe the NESBA rules in the B group are the right rules for that group. I wouldn't want to be passing someone who was just learning on the outisde in a turn for the very reason Meat said, sometimes B riders make quick, unpredictable moves and if you are on the outside of them and they do something like that in a corner, a bad thing could happen. Heck in the B group several times this year, while passing on the straight I had individuals move right or left on the straightaway 8 to 10 feet for no reason that I could see. Coming up on them at speeds that were 20 to 30 mph faster or more...it isn't fun. Twice this year, I got run off the outside of the track mid straightaway by riders moving to the outside in unpredicitable ways. Didn't go down on any of those off track excursions, but it is scary when it happens. I wouldn't want to deal with that in corners since you aren't going to be able to save it if you are run off while leaning over.
With that said in I while passing in the corner on the outside....you need to keep in mind that the rider in front of you is going to drift to the outside exiting the turn and as such you need to be prepared for that while passing him. As long as the rider in front of you is running decent lines and not being unpredicitable, you can safely make that pass.
All in all, I had a ball in B and I think it was the right thing for me to start there. I didn't have enough track experience and I learn the safe ways to pass in B and how to make better passing decisions. My comments above to the original poster who asked the question were directed to his 6 track days he already had and if he was consistent (with his lnes) and made good decisions (being predicitable), and was smooth, starting in I was probably a better decision.
I wish NESBA did have a complete Newbie group...that you had to go through or perhaps a newbie skillls day you needed to go through before jumping up to the normal B group. I know it probably isn't practical to do that, but separating the better B riders from the folks just starting would make it a bit safer and I also think it would make the day more fun for the riders who are in B at both ends of the skills spectrum.
But with that said, I think NESBA does a great job running their track days and is clearly the safest group around to ride with no matter where your start.
Hey and bring on more Skills Enhancement days next year. That format is awesome!
