I think you are all playing with me... "Crashtech" is listed twice for Sidock on Free-Dc. So I am double checking all the stats. May not post 1st half stats until tomorrow as I am cooking and the wife is hungry and if I take much longer I will be in big trouble.
Plus, my twist needs some major work to help level the playing field, but here it goes for now. Note read Rule #2!
Goal 1 of DC challenge. Generally reward more output that each player achieves. It is all for the science!
Rule 1. 1st Half points are based upon a maximum of 100 points. Highest = 100. Next = 90, and is the player with the next highest percentage of total points.
Rule 2.
In this challenge, penalize a player if their output drops over the time of the race. So in this case, you lose your 1st half of the race points if your 2nd half output is less than the 1st. (Though you don't lose any points earned by recruiting a new player. One new player recruited = 20 points).
Rule 3. Your second half points out of 100 equals your percentage increase over your 1st half points. (Big problem here is that not everyone started at the same time for multiple reasons, but the challenge organizer is one of the largest problems

For future challenges there needs to be some factor for those that start late.
Rule 4. (This is not used in this challenge, but to help achieve Goal 1) There probably should be some minor incentive to make sure output does not drop over each stage and some way to balance out those that start late?
I have been thinking of a few Rules after the start of a race to keep a challenge interesting and maybe the later rules can change based upon some random factor, but none of that made it into this challenge.
