the promotion period

What does it mean to win prizes during *The promotion period*?

that is an odd one. I think what it means (not for sure) is that when your streak is active is kind of called 'the promotion period'. For instance if you win or push, your 'promotion period' restarts to 7 days to make a pick. It seems like that is very old (March 30, 2010).

The promotion period is referring to the contest. They reserve the right to end the contest at any time although it's been going on since 2005 I believe. 

i thought the limit was make a pick every 4 days...or 3????

Could i get an understanding what determines how many days you have,,,before you have to make your next pick....sorry if i missed the explanation...
