I like the idea and will be happy to contribute. One thing to consider would be to make winning worth a little more; at least 13, maybe 15.
I had thought about this kind of thing in the past. I'd like to add bonus points for beating to drivers; i.e., extra points for finishing ahead of drivers who are ahead of you in the table? And, dropping points if you finish behind? Of course (the reason I've never done it), it gets complicated.
