Gambling has never been more fun when a gambler can fully keep good track of his gambling history. The casino has a section for activities and that section keeps a record of their gambling activities which is very useful for a gambler. Going as far as creating a spreadsheet for keeping a deep record could only mean one thing, which is the idea of taking gambling as a career.
1. You can find what bet types you excel at. By tracking your bets, and grouping the data by bet type (spreads, totals, moneylines, props, parlays, teasers) you can quickly find out what types profit you the most, and which ones cause you to lose your bankroll to the books.
This is good, and it is for those who gamble with different casino games. For me, I stick to sports betting alone because i already figured out that am more progressive in sports games than any other casino games.
3. Spot any favoritism or biases you have. I spoke with a semi-pro bettor named William after the 2020-21 NBA season. Will told me that after the season, he broke all his tracked bet data down by team and compared it to the research he had done before he placed each bet. He realized that there were at least 15 times he lost a bet where his research had pointed him to bet on one team, but his favoritism caused him to bet on the opposite team! Crazy right? Think of all the biases that could be keeping you from making the right decisions.
It is wrong to pick a side to win because they are our favorite club. Being passionate about our club cannot make use win our bet. When we know our favorite team will lose, we should play them to lose if we can't then we should avoid the game entirely. Since playing on them will make us lose the bet.
