Actually I use a trick. There are members here who actually know what they are talking about, so I wait until right before the event starts (when betting closes) read through the posts (I try to get people to post if there hasn't been any), and whoever the members favor is usually the winner.
It's a 70/40 thing. Usually right 70% of the time, wrong 40% of the time.
Hell of a lot better than 40/70 or worse.
Now I will tell you, on the Super Bowl I took a gamble, and it paid off. Sometimes you have to take risks. Don't rely on that F next to the payout ratio. It's a sign of false hope to me. Don't go with the highest ratio either. Another sign of false hope for me.
Who ever has the most bets, yet again wrong. Super Bowl was prime example. Colts had over 60 votes, Saints had well under that. Who won? Saints baby! 66 users lost over 190K vBux collectively.
So yeah. That's my tips and trades/secretes.
+Thanks and +Rep if this helps?
