I and a friend watched one we play it every now and then just to be able to study it and we found the betting and card pattern it took 7 hours but was well worth it as we busted it that evening.
When that happen the whole system shut down and was rebooted the bot was still at the table but in sit out after a short time it fell from the table my friend banked over 600 bucks so it can be worth the hunt. ;)
