I just got my dialed in and thought I had the magnet set correctly. It seemed to throw around very well after my initial adjustment to -75. It has only been a week since I got the game but I was then noticing that it grabbed the ball, pulsed and actually threw it downward a bit. (Yes, this was in something like package drop that is supposed to whip it around). I then readjusted with the magnet test and got it working. Then in gameplay, it acted up again. I then tried so many settings during the magnet test that the magnet actually stopped working completely for 5 or so minutes. I can only assume that it overheated.
I now have it working that it slowly throws it around but I have no faith that it will work again tomorrow. I am almost afraid to touch the settings. This is really bizarre. Could it be that my magnet is overheating and affecting the performance with gameplay? I have a call into Frank but I am completely puzzled as to why I would see such varied and inconsistent behavior.
