Last year Belridge came 3rd and Moorebank was 4th. There was a crash in one of the semi final races and they didn't seem to run quite as well after that. They could quite possibly have made the final.

I have just been fixing up the round robin/seeding file from the event and will be loading it up soon. When I do, you will notice that the Moorebank have some ridiculously fast predicted times for a couple of their races which were held in about 10% sunlight. This is because they did really well in the low sunlights and the seeding formula used up until now has been based on results from previous years where there hasn't been a lot of data available at that lower end. It seems that I will be needing to make some adjustments to the formula in the lower sunlights.

Apart from that, the seeding formula seems to do alright. Only Moorebank, the 2009 test car and Killswitch with their track record on Sunday were able to go under the predicted times at various sun levels.

Thanks for correcting.

I thought the predicted time for Moorebank, under full sun, was 5 seconds based on their 10% light time, lol.
How can they be under?

What I meant was go under the predicted time of the seeding formula at the particular sunlight that they were racing at.

Yes, the predicted time for Moorebank, under full sun, was a 6.55 second lap based on their 9.8% light time to be exact. This is the ridiculously fast predicted time that I was referring to in the previous post.

Are you sure about that, because I can't find anywhere in the rules where it says that. Marc, maybe you could clear that up? Also if that's the case the tas car came off the track - ie guides were not in place, and then surely this qualifies for the car not being stable enough to race, and not being on the track...?

This rule isn't really all that clear cut and a decision is often just made depending on the circumstances. My line of thinking has always been similar to what Tony has listed there.

Section 7.7 in the administration regulations state that "If a car stops for any reason, that car may be restarted under the
marshal’s discretion from any point on the track behind the stopping position, but the car must not be pushed to restart."

This is however under Poor light/adverse weather conditions so I don't know.

Maybe we can add this to the new rules??

Just make a clean rule stating: If your car comes off the track, and doesn't impose the other car, you may place it back onto the track anywhere behind the part it came off.

I'm not exactly sure about this but with the St.Patrick's car I think the egg may have fallen out. I think it was then placed back in so that the car could continue the race.

To me this seems unreasonable, if the egg breaks or falls out the car should forfeit that race because it no longer has a 'driver'. If the car is allowed to continue with a broken egg or it is allowed to have it re-inserted mid-race, what is the point of carrying it?

Yes. I have the video footage to support your claim. The egg does however appear undamaged.

Whether this is or isn't allowed (I don't think the rules specify what is to occur if an egg falls out of a car and is undamaged), the decision was made at the time to permit the actions taken to go ahead.

If there had been some protests by the St Paul's team after the race, things may have been reviewed. This was however not the case as far as I'm aware.

This is something that probably needs clarifying in the new rules. For example:

1) A car will forfeit the race if the egg breaks and/or falls out of the cabin onto the track.

Also Marc speaking of videos when do you think you will get race footage + scrutineering photos up?

Cheers,
David.

The internet at home isn't fantastic so I will be loading things up from Uni. I hope to drop by in the next week or so.

A lot of the video footage can go directly up on Youtube from the camera but some clips still need to be edited and that will take a little longer.

The car scrutineering photos will be going up on the Tas Website.

I will notify everyone once I am done.

Western Australia, your home turf Redlands ;). Then maybe NSW or QLD in 2011.

It hasn't been fully confirmed quite yet and is still depending on a few things, but it certainly looks like it. If for some reason it falls through, Hobart is there as a backup.

Year 12s generally don't do solar car at Aquinas, which would rule out myself and Christian.

That said, with nationals in Perth, we may be able to hang around for another year.

Regarding the question of dislodged eggs. Rule 8.27 clearly states: In any race, a cracked, broken or dislodged egg will mean that the driver is injured, so the car will concede that race to its opponent. The problem is that no-one was watching for this in Melbourne. I saw several cars, including the second placed car, with dislodged eggs after the races but the races were deemed to be finished at the timing point and it was not clear when the egg had come out. Next year the race will not be over until the cars are stopped and taken from the track, so look out. If a car had a dislodged egg the other team should have lodged a protest at the time, as per the rules.
