What they have explained (in their words above) is that there is actually some math involved in the process of determining and advertising a purse payout schedule. For them to announce the (proposed, initial) payouts, they did the math by splitting the guaranteed winged payout over a fictional number of 64 cars and the guaranteed non-winged over 50 cars. They are still paying the same amount, but obviously if there aren't 64 and 50 cars (exactly), the math comes out different. In other words, if there are fewer cars, the payouts per position will be larger since they are paying out the same amount!!!! I seriously hope they get a USAC midget show at Badlands next year.
