Well let's face it, even really good darts whirlybird every once in a while, don't they ? But the short answer is yes, at higher velocities it magnifies any small inconsistency or flaws in the drag profile of any given dart. A little bit of extra glue, an asymmetrical dart head, dents in the foam, they can all make a difference as your speed goes up.

I've also noticed the same thing at the other end of the spectrum. As a darts slows down you'll often see a slight change in the trajectory. I see it a lot with Mega darts.
