You obviously didnt look at the lap times then, Eric. I believe the unnoficial lap record, courtesy of the transponder system, is now in the thousands of miles per hour, and no doubt you also didnt notice that some races, 3 I believe, were timed manually, because the transponder system failed. I hope you're more alert than that when you're marshalling! LOL. I dont believe that the competitors should be required to buy something, ie transponders, just so the organisers can find out whether the system works or not, that should have been sorted out first at the organisers and system suppliers expense.
