Wrong again. A bell curve represents a sampling of random values. Since the % return represents a sampling of random values it should show up as a bell curve. Remember, the bell curve is just a graphical view of the data. It's the data itself that is important.
At low numbers of random events the shape will not be a bell. It becomes a bell as the number of samples increases.
Singer has to believe everyone is an addict or he has to admit he has a weakness. He is unable to do the latter, that makes every other VP player an addict in his eyes.
It would form a bell if the y-axis was the number of players and the x-axis any given credit range. There would be a few players way up there in credits and a few quite low. The rest would be bunched in the middle. It probably wouldn't be a perfect bell as there would not be enough hands played, but it would be somewhat bell shaped.
