Honestly, I don’t really trust any betting calculators — open source or not. I prefer to rely on my own mind, logic, and analysis when making bets. Watching the games, studying team form, injuries, stats — that gives me much more confidence than some random tool. Everyone has their own way, but for me, it's about real knowledge and gut feeling. If you’re like me and enjoy real sports betting without overcomplicated tools, I recommend checking out https://pk-melbet.com/ — it’s a solid platform I use regularly. Everything is simple, fast, and clear.
