Some people go this far to analyze the game before placing their bet but still, it isn't a guarantee that you would make profit. Why much stress when we are gambling for fun. Gamble is all about luck, and if you think that it's by your analysis, you are wrong because in the long run, you will run at loss.
What I have observed in different bookies is that, their odds are always similar week with a little difference. Which means that if you are sticking ti one same bookmarker, it doesn't change anything. If you love the sport that you are gambling on, you will always want to be updated on that sport by watching or listening to news updates.
Analyzing is not a guarantee that you might actually end up winning, even though it would increase your chances of winning. Having a strategy is important but it's not always about it, sometimes winning strategies end up falling apart, gambling is a game of winning and losing, don't rely too much on your analysis otherwise you would get results that you don't plan for. The most important thing is to gamble responsibly.
