I won't try any longer to explain what may be wrong or what may be right, because it is beyond my personal knowledge, beyound the purposes of an user forum. Moreover there is people supposed to do that far better than me.
If you have further doubts, ask USSA or FIS for a written statement. That's all.
Let me just ask you a couple of questions.
1) How will you deal with all the problems related to matching the official TODs later on?
There is a good chance that you may get ties that "were" not ties, just because of a .001 drift between the official timing and what you sent to the scoreboard, to the pc, to the announcer.....
You may have also inversions in the results, and even a new winner.... eventually half an hour later...
What will you say? Will you tell 'em that "the official timing in the shoe boxes at the finish shows new evidence"?
If I were you I won't be wearing a windjacket that day. I would choose a bulletproof protection!
2) Nobody hads doubt about your intentions towards the athletes. But rules are rules, and you already do the best for the athletes by simply following them. "Best intentions" cannot help. NO WAY.
3) Sometimes there are so many easy solutions to get through....
-a cable reel..even half a mile would be not that heavy and cost just some bucks;
-a radio modem from BlackBox or Xstream may send you the daytimes to the heated timing hut:http://www.blackbox.com/Store/...ess/n-4294966713/p-0http://www.digi.com/technology...00_2400solutions.jsp
-finally, if there are wires from the start to the finish (you didn't mention this possibility) you can connect the timers by wire and then use your TED to send the serial output from the finish to the timing hut.
