Thanks to those who shared their experience on confirming cross country finish order.
Since this thread was originally about Race Results mats, it's worth noting that I can get a super tight finish line with excellent finish order accuracy using shoe tags. With the tag down low they "fly under the radar" and get picked up right on the line. There are reasons we are using bib tags for this particular race coming up but that is another story...
Another thing worth noting is I get really good finish order accuracy when timing bike races where the chip is attached to a number plate on the front of the bike. With running races bib placement is all over the place and I think that has a big effect on when the first read happens. At least for cross country we can expect uniform bib placement on the front of the uniform so hopefully that will improve the chip timed finish order. We are going to have a couple of volunteers getting finish order manually and also have a camera on it so expecting all to be well at the cross country race.
Also, here's a little trick you won't see on the Race Result website. If you need side antennas, stand the mat on edge. Did this for counting laps at an indoor track meet with athletes wearing ankle strap chips - MASSIVE coverage!! The setup pictured gave a little better than half a second accuracy compared to the official meet times done with a FinishLynx, plus we had splits for everybody on every lap. The main purpose of the setup was to confirm lap counts for an indoor 5k and 1600 with really fast collegiate runners and it was perfect for that.
