In his last article, Dancer says he was up 250K in 2000 at the MGM. Now that was the year that fueled his Million Dollar Video Poker book. It seems that if he won a million that year, with the bulk of it at MGM, then he must have lost a good chunk of it back to the MGM to wind up +250K.

Doesn't this jive with what you had previously mentioned about him losing half of his winnings back to the MGM? After finishing the book, you are left thinking he wound up plus a million, but clearly he didn't, so this comment by him would seem to suggest you were correct. The loss of half of the winnings somehow didn't make the final edit.
