WHAT IS THE WATERMILL SCORE?

Editor's note: Earlier this year All Left Turns introduced the Watermill Score, the four-pronged strategy that Sprint Cup teams should follow in order to win a title. In a follow-up story, we showed how winning a NASCAR title is like counting cards. This third post elaborates on the first two, covering why the Watermill Score is important and how teams can use it to affect race strategy.I.

CHAMPIONSHIP PROBABILITY TABLE: JOHNSON PASSES STEWART AND MARTIN

With the Dover race in the record books, just eight races remain until the 2009 Sprint Cup champion is crowned.

Another way to think about this concept is to use the analogy of counting cards in blackjack.The point in blackjack is that you have 52 cards in a deck, but only certain cards are worth points.

NUMBERS SAY CUP IS STEWART’S TO LOSE

With the Chase field locked, it is time to put away our Chase qualifying tables and break out our championship percentage probability tables. With 10 races to go, Tony Stewart leads all drivers with a 30 percent chance of winning the Cup.I kicked things off with a simulated model of 14,950 potential outcomes in the next 10 races. (Yes, this is what I do for fun.) Adjust for the current points standings (5,000 through 5,040) and we get percentages for who will end the Chase with the most points.R ...
