I'm just so curious, do you update it manually by looking at the accounts one by one? and I'm still wondering as well, why do you want to spend that much amount for the competition (many times already) but you do not want to spent few btc to upgrade the site to make it better than what you have now.
Do you think it is worth enough to spend so many btc for the competition but most of the players will just leave your site away after the competition ends and will be back again when there is new +EV competition? Because there is no good reasons to stay on your site for longer time. No offenses buddy, but I think you really need to make a wiser decision in spending your BTCs.
