Tom first off, your 1.8 was competitive this weekend, again, you and Josh ran the fastest laps of the race.
Regarding the waived off start. I have been through a few of those, If the the green is never displayed on the start then the restart should be two by two. If they do not send out a pace car then as you come around to the start finish you line up again and give it a go.
So they should have been showing double yellow at all stations meaning the race never started. if the green fly's then goes to yellow i think that would be a single yellow flag all stations then you its single file start.
One of the officials can chime in but that is what i remember from when we got three shots at it one time.
