• Yes, you do need a backup plan. We had very few failures for the first few years (average of one missed pass per season, for riders doing 11 laps, so 12 passes per rider per night x 50 riders x 10 events). But then a couple of the batteries started to run down and there were a few more, so we always kept a watch running.
    The circuit is set up as a strava segment which provides a useful backup as well.
    For the most part though, the system is much more reliable than a human timekeeper. We found that when we hosted some competitions with a very experienced timekeeper in charge, he went with what the computer said, rather than his watch presses.
    The biggest problem is human error: sometimes new riders have not realised they had to put a transponder on, done 11 laps flat out and expected to get a time by magic!

  • Yes, we have the 11 laps problem @ the Velopark when riders don't stop when we call them off. It seems that you don't replace the time keeper role@ a TT you just automate some of the work.
    Frank, I am putting the proposal to go with the "My Laps " system to our club's committee. Once they have decided it would be good if we could perhaps discuss with you club how you system..
