Winners and Losers

[Monty Cantsin]

In the theory forum someone started this thread about what percentage of the player population are long term winners.

Specifically, people are wondering why everyone's database breaks down around 60/40 losers/winners and what the significance of this number is.

I don't know enough to say but I have a feeling that a lot posts in this thread demonstrate a fundamental confusion about some basic principles of statistics.

1. Is there a definitive discussion of these issues somewhere that could be linked to?

2. Do any of you statistics types want to come by and drop a little science on us?

Thanks,
