The maximum number of chips that can be added due to a color up is 2x(chip value)x(# of tables). I showed in my blog
www.liontales.com that by the time they played down to 27 the very maximum theoretically possible in extra chips due to chip races was 50,900. (The likely total is far less than that.) The reported chip count was more than 500,000 over 87,730,000.
By the time it got down to the final table another 1.7 million chips had been added. The only color up that took place between 27 and 9 was the 5000 chips, which could only have added another 15,000. At the final table they may have raced off the 10,000 chips, which could add at most 20,000.
Gross negligence or cheating are the only explanations.
