I seem to recall something about Terry changing the numbers to reflect the number of non-member plays.
He had determined that for every registered member playing a quiz there were two 'guests' so he recorded the numers x3 to give a more accurate reflection of how often the quizzes were being played.
Of course the site has grown as well.
