It's pretty rude to address a person that took the time to analyze 12,000 MMA fights as 'some guy.' His name is Vik Singh, and his official title is 'some guy that is a glutton for data mining.'

He extracted a gargantuan amount of information, and it seems like he will use this data to make an absurd amount of money in online betting. You can check out his scientific blog right here to see what he intends to do with this data, but check out the extraordinary facts he discovered in his arm-chair mathematical experiment. [Source]
