Chip timing is not perfect, but it is really close to perfect and way better than most everything else. It just bothers me that it doesn't conform exactly to what the rules say about finishing.
Maybe long term we can think about having race jerseys for each team have a rectangle in the lower middle of the back with a contrasting background and a number (white and black work). Above that is the name of the race team clearly displayed. Now every rider is identified by team and number within the team.
