So Darren Brown claimed to have guessed all six lottery numbers by taking the guesses of 24 people and averaging each one to get the correct one. This is bollox if this was true we could all be lottery winners by just getting 23 friends/relatives together and guessing each number and averaging it among all 24.

If Brown really guessed the numbers rather than perform some camera trickery then why didn't he display the 'guessed' numbers till after the draw was made.
