In their defense, the article doesn't say that the Borgata claimed that there was a cheating ring, only a gaming analyst.

Ultimately, the article makes for a good story with the possibility of a cheating ring but it has few facts. Boyd gaming probably has a pretty darn good handle on what their ROI should be from their gaming at each casino they own in any given month. there's history and multiple properties to compare with. they, of all people, should be well aware that their business is subject to random swings towards the player's favor.

what is a bigger reason that wasn't even mentioned, is the absent of even a single whale and how it can greatly affect a casino's quarterly returns. if just one mega whale didn't show up for his usual trip then everything can be skewed. financially, it would be a better way to report their earnings if they could isolate the top 5% winners or losers from the figures to see what the casino earns from the majority of their customers. not sure if they could but if they have whales that can win or lose hundreds of thousands or millions in a single session then clearly that will skew the results.

oh well.
