Great attitude to sit down and reflect on your small spill. I ride alot on the track and I'm amazed how often some people crash. They always blame something. My last crash was 2003 and I really took a hard look at myself and guess what; it was MY fault.
One thing I learned about beginners when teaching the MSF course. Lots pull in the clutch with the throttle still open. This causes the engine to race and new riders are startled. In their mind, pulling in the clutch caused the engine to race so the quickly let out the clutch causing the rear to spin. I always made it a point to tell riders, "if you hear the engine racing don't react, take a second, think and roll off the throttle before doing anything else.
