Hello all,

Here are the results from both Saturday and Sunday.



I will also be attaching a car data file with car weights, panel powers, etc once Stan and I have it completed.

Had a quick look at the results.
You've done a great job Marc. Kudos.

Although the seeding formula isnt entirely accurate, i personally think its enough how it is.

Yeah I know it's not 100%, but for a consistent car it's pretty close. I will be fixing it up at the lower end for next year's event, but apart from that like you say it's enough.
Car seeding doesn't usually turn out too bad in the end. Particularly with the little data that is given to work with from the Round Robins. It's certainly a lot more accurate than what used to be done a few years ago.

The problem this year was that basically all cars, with the exception of Moorebank Stealth, the test car and one or two others, were really dropping off in performance in the lower sunlights even when they were doing alright in good sunlight.

I have collected data from every car from both Saturday and Sunday and arranged it so it is a bit easier to analyse. Here is a copy for anyone that's interested.

I just had a quick look at the seeding curve. Personally i think its accurate enough.
The curve really needs to be based on the performance of the 'average fast car' as opposed to the fastest car. Do you agree?

Yes, that's more or less what it's based towards at the moment. The curve isn't quite based on the fastest times and there has been several cars in the past few years that have bettered it.

Marc when do you think the car technical data would be available?

Within the next week I hope.

I have sent Stan the competition files from the event so he can include car times and positions as per usual. He sorts out the placings 1 through to 32 based on the when cars were knocked out and then times per unit sunlight.
Because I have sent him an extra bit with that basically already done, I don't think it should take too long.

He will be sending me a draft copy to check over when he's done. Once everything looks in order, I'll post it up on here.

Reason i ask is...
I want to compare the performance of the high powered car, to the cars using low power setups. For some reason all the higher powered cars just seemed to be quicker.

I have just received the first draft of the car technical data from Stan. There are a few slight modifications and additions that still need to be made, but hopefully I'll be able to get the final version online within the next few days.

I agree that it was rather noticeable at this year's event that most of the top cars were all using high powered panels.

Whether this was just a coincidence or not, I'm not sure. I think I'll be looking into the matter a little more. Ian will be running some dynamometer tests over the summer on some of the newer cells and panels available so that will then allow some reasonably accurate simulations to be run.

Hello all,

Here is the 2009 nationals car technical data file with car weights, panel powers, etc.

When you sought the list on chassis weight the WA cars are the lightest.

Aquinas, Girrawheen and Winthrop take up 6 of the top 7 places with their two cars each.

Hello all,

It's taken a while, but scrutineering photos from the 2009 national event are now on the Tas website.
