Trackers are clearly inconsistent. the TipTop one is my favorite with its interactive interface. But which one is accurate?

Early on lots of griping from everywhere that the contest's efforts to provide a "live" internet experience sucked. It of course would be easily solved if some nice sponsor would pony-up several hundred $$$ for the technology.. But I'd guess the actual look-in audience return isn't enough to move anyone's budget.

Hopefully some day the best tracker will be able to downlink flight/speed data, gin it into a a readout that would inform us who actually is in what place in the task standings.
