A topic as old as the day of the very first track day with different skill groups...here we go
Advanced group is like doing calculus, intermediate is doing algebra, and novice group is doing simple addition/subtraction. If you can't add or subtract, you really don't have any business doing anything more difficult.
Novice group should never hold you back. Sure, at some points the passing rules might prohibit passing at a certain point in the track for a short amount of time. But are those bikes really holding you back? You said it yourself - you have a big bike and able to run bikes down on the straight (drag racing). Why can't you just pass them on the brakes with all that speed? A simple straight up and down pass, either coming out of a corner or going into is one of the first fundamental passing skills you have to master before working on outside, let alone inside, corner passing.
It's very, very easy to pick out a rider that needs to move up. Maybe that's you, maybe it's not. If I had a dollar for every person that thought they were ready for a bump and were not, I'd have several thousand dollars at this point. If I had to pay $100 for every person that said they were ready for a bump and they actually were, I'd still have several thousand dollars.
The hot pit lane is a love/hate thing for me. It does get you clean track fast, but doesn't do anything to further your passing craft. More often than not, it's the riders inability to setup and plan passes that's more of an issue than the traffic itself. Don't get me wrong - there are some CRAZY track days where honestly it is just plain congested. For sure. Not denying that. But the overwhelming majority of "traffic" isn't really traffic at all.
Scan ahead, learn to read the bikes, and adjust your riding as needed to get around those slower riders:
