David, whose last name I can never remember, from Kings Island had a very good point about that in regards to Sonny. And he is correct. The important thing isn't how many hours you run the ride or how long you do your testing, but rather that you complete a full testing process. Also, some tests may be conducted in a different manner on Sonny than on Millennium Force. For example, on Millennium Force, the reach envelope testing was done with a pull-through; the implication last week was that Sonny wouldn't get a pull-through, but rather that the envelope testing would be done as the ride operated: put the envelope testing rig in the car, dispatch it, and see if the whole rig comes back in one piece. If the test is successful, then it's a faster way to complete that testing procedure (finish in three minutes instead of three days). If it is unsuccessful, then it takes a little longer to find the problem.
The main thing is that all of the issues that need to be tested get tested. How long it takes to make those determinations is really unimportant.
Remember also that a big part of Cedar Point's testing procedure is to get the cycle timing worked out so that they can know just how quickly the crews have to work to hit interval. That kind of testing serves to allow the ride to run more efficiently, but does not necessarily reflect on the safety of the ride. It's very possible and perfectly safe to open the ride before all that stuff is worked out; in fact it will work itself out in the first few weeks of operation.
Translation: I don't think either park is really doing a more thorough testing job than the other. It's just that Cedar Point can be a little more relaxed about putting Millennium Force through its paces than Kings Island can be with Sonny.
