G'day TonyG,
Thanks for your idea, after consideration,  we think this  embodies the spirit  of your  idea in a simpler more manageable format.
A SWEEP TIPPING CONTEST  FOR THE SEASONThis is a sweep and similar to footy tipping. If enough people are interested ( Minimum of 10 participants ) I would be prepared to run it. It offers unlimited  entrants.  It is non - profit making. All A$ collected will be used for prizes and maybe boosted by a bonus. 
People choose their own driver, making it  more a test of skill.  You can choose a different driver for each race, if not chosen before the deadline - your previous choice will roll over to the next race if eligible.
it would work like this 
A$10  per race = 190 Achat Dollars for the season, 19 races 
You choose your own driver
Points are awarded  as below 
Position   Points
1     =   25
2     =   18
3     =   15
4     =   12
5     =   10
6     =    8
7     =    6
8     =    4
9     =    2
10    =    1
Pole Position    =   10
The person who has the most points at the end of the season wins, or if  two or more are equal,  split the prize.
1st Prize = 60% of total Prize Pool
2nd Prize = 30% of total Prize Pool
3rd Prize = 10% of total Prize Pool
With 19 races left in the season making the maximum available points 
19 x  25  for First  and a possible  19 x 10  for pole  = 665  for  the season.
