Other: Sports betting, pendulum

Hi, could you please tell me how one can make money on sports betting, football for example? Lady Pythia said it's possible through a pendulum, but I'm having some trouble working with it, even though I charge it with the translator rune Perth. How does one actually work with a pendulum — are there any books? There's nothing worthwhile on the internet. Are there other ways to find out match results? Tarot is even less clear. Maybe there's a Demon who could cooperate on this matter? I don't need 100% correct answers, but at least I'd like correct answers to prevail. I don't want this to be a lifelong source of income — I understand I need to learn business and investing — but I see this as starting capital. I understand that you need to win wisely, rarely but precisely, so the odds don't cut you down.
