I heard about it from a guy on the ZX10 forum, apparently one in the group. Bottom line is when passing, cars, bikes, whatever you take a chance on the vahicle in front doing something unexpexted...When you pass multiples the odds go up exponentially as those way in front have no idea what is taking place behind and you cannot know their intentions until you reach visual, which usually takes place at elevated speeds (you all know how fast a bike will accelerate in just a few car lengths).

Just be patient and pass one at a time!
