Such a strategy in my opinion has only sense for players who have lot of money and if they play more then 1 event on ticket. There is no doubt that chances for winning with +3 goals represent a nice advantage, but problem is that such low odds almost always takes the player into losing at the end.

For example if you start with 1000$ and bet on in total odd 1.05 per ticket, you risk all that money for 50$ profit. Although the chances are quite high in favor of the player, to win 20 times in a row is not an easy task. Very risky strategy, and in my opinion unprofitable in the long run.
