Drag racing isn't rocket science. I'm sure its hard to run really fast really consistently, but as far as making one great run, I can't see it being that hard if you can make dozens of attempts. Most people really don't care how fast their car runs stock, and so generally just show up at a test and tune once or twice.
Also, the grip level of many (most?) tracks *****. The ones I've run at were all worse than the street. I'm going to try to run 10s in my ACR, but with my Racelogic, not at a drag strip. At local strips, the grip level is unpredictable, the walls are close by, and the workers have a knack for not noticing or cleaning up all fluid spills (unlike a street surface, when fluid spills on a polished drag strip the grip drops to nothing).
