I had a great deal of road racing experience (18 years, 4 years as AMA Pro), and thought I could run a record pace during my rookie weekend (2 day). I was told I could get "special" consideration by having a yellow sticker on my bike (put there at tech inspection) and mentioning it to the starting official. What I didn't know was that this was going to make the race director follow me down the track in his car. Add to that I had "issues" during my first run. After my run, a clearly annoyed race director climbed out of his car, came over to my bike and ripped the sticker off my fender while mumbling something about how I took too long to turn out. No non-rookie license for me. 8^)) As it is I ended up coming .7 MPH short of the record (minimum actually) the next day and I knew I could get the record during the next meet which I did.
What did I learn,
1) my road racing experience did nothing to prepare me for racing on dried mud.
2) most SCTA procedures are distilled over time and there are reasons for them.
Now maybe if you have Bonneville experience you may not find El Mirage daunting.
What my first run was like:
I was racing a bike I had run in AMA Pro-Twins 25 years earlier, but in the ensuing 25 years I had broken my left ankle.
Not having run the bike in anger, I didn't realize that my injury made it tough to shift.
I missed the shift into fifth, and then proceeded to lift my entire leg to upshift, missing 5th again.
Having time to over think my conversion of my old road racer into an LSR weapon, I removed seat foam to shift my weight back for more "traction". Stupid in hindsight as it made it even harder to shift.
The leg angle issue together with the fact that now I was hanging onto the clipons with all my weight rather than having the seat foam support my weight meant that every motion of my leg to try to get the bike into 5th caused a mini-speed wobble/tank slapper.
Add to that my inexperience, which had me looking down at big black lines (rubber laid by cars) and thinking "I'm going at a low angle to ruts, I'm going to get into a tank slapper and die".
In reality they were not ruts (as revealed by a track walk), I survived, but i really didn't deserve a license at that point.
Maybe you do, no harm in trying. YMMV
