Yes. They do have a lot of systems or methods for predicting games.
Yes. They can be conflicting.
However, I only use their Best Bets to get the cream of the crop for each of their systems. These can be conflicting too. But then they would cancel each other out and I would not wager on the game if they conflict.
I also use their UPM which gives a percentage for the games based on the matchups. Anything at 60% or above, deserves a play.
So far this year, these have made excellent plays.
Hopefully, the above helps.
