Hi,
I did see the results on the net, and was cheering for you guys
I don't know what you mean by factors

I think the NSW race may work under completely different principles. It is not regularity, but is an outright race (ie fastest cars win) , with a secondary handicap
I know last year we were in with a chance of winning handicap, or at least coming 2nd with 15 minutes to go, until someone went too fast on a couple of laps and blew our handicap

However, it was understandable as he was racing the team ahead of us for position on the road, and therefore for the lead
Cheers
Robbo
