the odds seems to be not matching most of the sites

Bet365
Talkbet
brotherbets

just to mention a few

Do the fair odds come from pinnacle plus the vig, or are they scraped from elsewhere? There are quite a few fair odds which don't align with pinnacle and I would like to understand what I am missing...

If anyone here does bigger stakes/different techniques, please could you drop me a DM and we can discuss approaches? Or ask me to speak to you on discord and see if we can help each other get as much EV as possible
