With regards to the timing system:

Watching the Pika A/SDC C heat, as I know we all are, I noticed that the start had a double beep. Was that just a hitch in the starters finger? In most events that double beep indicates a false start, but clearly none of the pushers thought twice about it. My only concern here would be what if there was a false start in a heat this year? Especially on heats like that where the yelling/cheering starts immediately, would they even hear a second beep? I feel like we should have a system in place next year that makes a false start very clear and easy for the starter the convey. Maybe even a flag the starter waves to some course marshall up the hill who runs into the middle of hill 1 with a red flag waving it so the pushers stop pushing (the drivers don't need to break here, and we should tell them they shouldn't.. just the pusher should stop).

Wow, air horn doesn't even occur to me, but makes perfect sense. Yeah, if it is such a blatant false start like that one was, it's easy. But I'm talking about someone going much closer to the beep where it's much closer a judgement call of the starter. Still, air horn seems a good solution unless others have an idea.

Hmm ok. Well looking at the start it seems like nobody moved early. Maybe one of the buggies was over the line a bit? I thought they had a judge w/ camera on the start line for that purpose, but perhaps I'm mistaken.

Bringing up this false start and the timing system reminded me of something that should be corrected next year:

On several of the races, the announcers counted down with the starter, coming clearly over loudspeakers, and obviously not in sync. This could easily cause a false start, or at the very least, confuse the H1 pushers.

I saw the Pioneers A pusher false start in that heat with Pika A & SDC C.
(The difficulty of fairly judging false starts on our course, and whether it is fair for a slower team to cause a faster team to have to restart is a separate subject)

The beep box we had will ignore a second button press if you press it too quickly, but it will accept a second press some time before the first beep finishes sounding (which takes about 1s), but I could never figure out any logic to how much silence there would be before the second beep (it was .5s-1s when I tested it).

In the preceding heat Fringe C false started. The two beeps were about a second apart, and everyone stopped & reset.

In the Pika A heat, the two beeps were a tiny amount apart, and none of the pushers noticed. Some spectators heard it as one, some as two.
The megaphone is highly directional, so by the time the second beep finished, the pushers would have been far enough up the hill not to hear any further beeps.

As the starter, I can only signal for the heat to be reset in case of a false start. If everyone continues the race instead, it is up to the judges to call the DQ if they see fit. Since both SDC & PiKA started cleanly, I don't think it affected the outcome of the race, unless the Hill 1's had a moment of indecision.

This issue of ignored false starts is one that we were worried about when settling on the current timing system, with no clear solution. Any suggestions on how to improve it would be good.

It is clear the current system doesn't have enough volume to be heard over the start line cheering. Using an additional megaphone pointed up the hill would be good for next year. Between holding the megaphone for the countdown and the button for the start, I didn't have any free hands to hold the airhorn if we had one and the time within which a false start has to be signalled is short enough that having a second person would take too long, and reaching over to hit the airhorn might take too long.

I suspect the solution is to do the countdown over WRCT (the guy with a mic is there already) and have a dedicated megaphone or two to amplify the beep like we had on truck weekend.

An actual starting gun would be more clearly audible and have a more predictable interval as the false start signal. The trouble is that there is a small chance that the gun will fire but not trigger the timing system to start automatically, which is a problem the beep does not have.
