Regarding the daily double, how do they decide where to place it?
I know they usually put them in one of the the last two spaces. I understand the DD needs to be somewhat of a mystery but since Arthur Chu has been winning and obviously searching them out it appears the producers seem to be trying to hide it from him. Today they wiped out the whole bottom of the board before it turned up in the 600 dollars spot. Same thing for Double Jeopardy.
Back to my OP, is the show purposely trying to keep the DD from contestants as long as possible? if so, why?
