Testing chess players – for what?

You can win ChessBase vouchers worth €350. Deadline: June 28th 2009.

Thank you for participating in our survey! We are conducting a little contest:

Your task is easy: we just want you to give us a number between 0 and 100 inclusively. The number need not be an integer. You have won if your number is closest to 2/3 of the average of the numbers given by all participants.

(Example: If there are only four players participating and their chosen numbers are 11.9; 23.45; 40 and 68.65, the average of the numbers is 36 and 2/3 of the average is 24. Here, the second player would have won.)

The winner gets a voucher for Chessbase-products worth 200 €, the 2nd and 3rd place will be a voucher worth 100 € and 50 €, respectively.
