I think it's ridiculous that the polesitter can "jump" (and be penalized!) the start. I've watched races from darn near my infancy (I'm 55 this week!) and the polesitter has always started the race somewhere in four. It's worked for decades and now they change it. Put the chalk line on the track and when he crosses it, he can start the race. There have been several "restarts" this year due to this stupid rule. Letting the polesitter start the race will eliminate about 90% of the restarts at the outset of a race.
