Before you consider sticking to your own decision or following instinct especially in sports bet, be sure to take the risk and ensure you have the money to waste at that point, because obviously those high number of predictors are always 80% accurate. It is always better to follow them and loose than to go with your judgment and lose at the same time. If you lose following your mind, you will always find yourself to blame because deep down, you know it was avoidable.
I have never gone against majority in gambling, although most majority opinion has led me to failure and I wish I obeyed my mind but thinking back to the times obedience made me win, I never regret staying with the crowd.
I think you should have known by now that gambling is a game of risk and it only takes a risk taker to stick by the game and as succeed, I dont understand what you mean by the game could by a loss can be avoided, what is meant to happen will always happen in gambling and this has nothing to do with going with the decision made by predictors. I believe you have seen predictions by almighty predicators go wrong.
For me, I have no business with predictions made by majority, I have learnt to be self-independent and I pays me off anyway but to those who depend on strategies, I advise you always stay with the crowd knowing that majority they say always has the vote.
