How good do you need to be at Bejeweled 2 to make playing on cash sites like King.com realistic?

My scores on the game are decent: typically 25% in the 5000-7500 point range, 50% in the 7500-10000 range, and 25% 10000+, but I see some amazingly high scores. If anyone plays the cash games on King, how high do you need to score to have any chance at all of breaking even or coming out ahead?How good do you need to be at Bejeweled 2 to make playing on cash sites like King.com realistic?
