I once had this guy coming around to bug me with weekend fixtures for coupon draws... Not until someone volunteered to stake heavily on them odds, just to prove to him that the authenticity of his games weren't guaranteed. Since he wasn't in a position to wager the games himself, the agreement was that if anyone wagers and it doesn't cut, he'll have to pay for the loss.. "I was surprised when he readily accepted". His confidence threw me off, but something kept telling me that he's got too much ballsiness for it to not.
Most of those forks knows exactly what they are doing and most times when they want to go into agreement with you on picking the games, they make sure that the percentage that is collected on your winnings are much higher than what they pay back if the bet becomes a losing one, so for that they are always at advantage regardless and since their know how the thing work's they build some level of confidence in their game's and boosting about it becomes one of the priority in other to convince their potential clients.
Don't also forget that, this is his business and so he have long term experience in those predictions and how it outcome always result to so you shouldn't be surprise seeing him making such confidential statements.
Long story cut short, it was a win! yes, it became a surprise and infact, a mystery to everyone that his prediction just delivered as though he arranged with the fixed draws -- 6 draws came through and since then, he kept making predictions on that premise, but the opposite was the case for everytime he wrote down random numbers. Infact, he has never won since then!
Why do people see themselves as a reservoir of unpredictable games whenever they bag a huge win in the midst of others?
Take the first winning as luck, and every other winning as experience, because that is what it is, there is no way that such a predictions will ever give you steady winning, because there is nothing like a sure bet anywhere and all bets are subject to luck and loses, that is why you shouldn't get carried away when there is any first winning from such predictions.
