You bring up a good point. There is no way to track for certain if a book releases every single wager they get to sportsinsights. Here is what they say about it...
Why would any sportsbook allow Sports Insights to display this information? Doesn’t this information hurt the sportsbooks?
This is one of the most popular questions asked. Let's just say it wasn’t easy getting the ball rolling. It took Sports Insights over a year to convince the original participants to allow the release of this information. It basically comes down to the sportsbooks wanting and needing to attract new members. The sports betting industry in general believes that the availability of betting percentages will soon become as common as standard betting lines. Sports Insights is the company that finally put all the pieces together and broke the ice. The sportsbooks that participate with us feel that members knowing which side the public is favoring will not hurt their business model. Bettors still have to pick winners. Think of this in another way. Why do sportsbook advertise on sites/phone services (touts) that guarantee winners? No matter what any site guarantees or offers, you still have to win. Sports Insights’ mission from day one has been to help its members make informed decisions based on facts. Always remember, any information is only as good as the person using it.
If you use a couple different sites you can get an accurate gauge of where most of the public money is coming in from. But you can't just blindly fade the public. You'll be just as lost as them. Even the worst bettors will hit close to 50%. You still have to make a case or angle towards your play, if the public is hammering the other side, then it's icing on the cake. Blindly fading the public is foolish though. Just use this as one of many tools. :toast:
