Maybe it would be better when there would be a "master" dot-watcher who gives the penalties during the race. So, you would know it already at the finish line.
Given the race doesn't stop, that's a pretty big job. As it stands the many dot watchers can report infractions to the race organisers. Problem is, they are manning CPs so probably don't have a lot of time to notify racers/public of penalties.
Richard Dunnett is Rules Monitor according to the manual.
So they do effectively have a master rules dude to confirm stuff. Whether or not he's notifying people of infractions during the race is another matter.
Well, I hope it's mentioned because arguing about placings after the race is finished sucks for everyone.
