Even without realising you probably bet a certain way. This may be the case if you don't assess your bets. It's good reason why you need to take note of each and every wager: course, code of racing (Flat/NH), betting odds, going... The more info you detail the better. It will help you consider, perhaps, the strength and weakness of your betting day, week, month or year(s).
It is all too easy to bet without thinking. Automatic. Perhaps subconsciously you have a losing pattern which is blighting your success without even appreciating its affect.
If you are winning money, you may consider you don't need to investigate. That may be a mistake because minor improvement can make a huge difference to your fortunes. If you are losing consistently, this assessment it crucial. Review your bets. No need to obsess about it but be mindful.
You don't need to do anything there and then but just take note.
It might be: ''Another odds-on shot, beaten''
''Every time I bet on a double-figure priced, the horse runs horrendously''
''Soft ground. Why do I keep betting when the ground changes?''
You may be quite happy with your bets and consider they cover a variety of bets and money backed.
It is possible you notice that when you increase your stake you find a loser. Perhaps after a couple of losing bets you half your stake. Sod's Law, it wins.
There is no right way to bet, because everyone has their own approach, likes, dislikes, sport, bet type...
But within that range you may just notice an anomaly.
If you can weed out one or two weak bets you can use this money to bet on your greater chances.
For that reason, it is good to keep a diary or notepad and make assessments throughout the season.
