The fact is that no two machines play alike, so it would be impossible to hold truly fair and balanced (Aka Fox News) online tournament settings.-Factors such the age and durometer of the rubber, is there a cliffy protecting a hole that makes it more difficult to hit, is there any drop dead foam or tweaks done to make the game play better, how much wax is on the playfield, slope, pitch, floor surface, climate/humidity, etc. These factors all affect the way a game plays. The sensors required to monitor such factors would be more expensive than the game itself. I do think online tournament would be a fun thing to add to a game but it would have to be for novelty purposes only.

Even if you take cheating out of the equation, it's still impossible to make two games play exactly the same to make it "fair" for competition. Players need to compete on the same machine during the same time period to make it as even as possible. That's why players at tournaments always compete on the same exact game vs. competing on seemingly identical games placed side by side.
