With STT or a local shop that runs track days, I'm a mid-pack Intermediate (on a good day). With someone like NESBA, faster half of Novice probably. Didn't do any track days last year, so I'm probably rusty/slow/cautious. Never was one for putting the hammer down on straights (plus I'm on a slow naked bike), but do OK in the corners. I'm mostly looking for personal feedback on what I'm doing right, and what I need to work on. Not worried about lap times per se, just riding smoother/better.
I suppose you enjoy PIRC then with its relatively short straights and hilly turns. You should be good for Level 2 then.
One of the best ways I've found to improve skills and keep them fresh is to hit a nice clean parking lot from time to time. Find one with little islands in it and make up a little slalom course. Do circles, figure eights, braking drills, etc. Really helps get a feel for the bike and prevents rust from building.
