how about if we raced for 20 scored the race and the next race we started as we finished in the earlier race? this would be the same as that but we would start w/ the lead we had @ the end of the 20. i see no issue in giving 100 points 2 times for running 2 20 minute races as one.
obviously this only seems populare amoung a few. so i'm not sure how this will work out.
