Patrick,
You DONOT have to model to win. Like FTL said pick one track and stick with it, no modeling, but complete at least 10, 20 race cycles at the same track. Modeling in my opinion is for those having a lot of time to do such. I don't model because I don't have time but I'm still a winner. I do good to get to the simucast a couple of times a month since Texas can't bet online.
Dude, I know that you are struggling but take the advice of previous posts and follow their lead and advice. I dare say that most every one on this site has been where you are, certainly including myself.
A good methodology for me is to simply follow Bill V's procedure. It's simple. Remember KISS!!!
Post again when you have about 5 cycles done. You can do it but you must stay FOCUSED.
Good Capping,
Bud
