Gary - (see my comments above)
We did leave a bigger gap between cars for the times runs.
We should of left more it looks like. Next time we have such distances between corner workers I'll monitor it more.
Also, I'll talk to the corner workers to let me know when they can't get the cones picked up quick enough, call start and we'll make adjustments. Maybe that happenned but we'll monitor it more next time we have such large distances between corners.
