I'm not a big fan of chip timing myself, though I do think it has its uses, especially for mass participation events. That said, I keep coming back to one thing, the lack of reliability. If a timing system can't reliably time all athletes in the event, what good is it? I guess I just don't get it. Why is it gaining in popularity, even before it has proven itself to be able to reliably do the one thing it is supposed to do? Even ignoring the other negatives on it, shouldn't that alone be enough to convince race directors to go with something else?
