These ratings are for imformational purposes only. What YOU choose to do with them is your business. If you feel like going to Vegas and betting your house on these numbers, that is strictly YOUR choice. I am NOT liable for the stupidity of your decisions.
That said, I also don't know when math guys got so preachy. I really could care less if you gamble, and gambling is NOT the root of all evil as some of these bible-thumpers say. If you are a problem gambler however, contact Gamblers Anonymous immediately.
