since 99% of you are well beyond the point of the MSF course
Not really. Anyone who believes they are beyond the basics has a serious reality disconnect.
One of the worst things I sometimes see coming from people who took the MSF class is that there is a mindset that they were trained and are safe and never have to practice that stuff again - it's the same attitude that comes out of drivers training. What they don't realize is that the course they take is the minimum concepts of the basics which barely gets them around an empty parking lot without crashing too many times.
To be safe, you have to stay proficient. To stay proficient, you have to practice regularly - as in at least once a month. Quite a few of us do parking lot practice on our own regularly even though we have years and even centuries of experience. I don't know about others however I train myself to a higher standard each time which results in dumping the motorcycle regularly - they're typically slow drops however I still have to pick myself and it up. If you have someone to analyze what you're doing, great. If not, you still have to practice and analyze your own proficiency objectively.
