I said most accurate when not accounting for variations such as seasons, price cuts and software, etc... When you take those into account, a much more sophisticated formula certainly comes into play.
The problem with Masterb8tr's method is that it continually narrows the sales gap disproportionally to the actual sales.
For example: If PS3 outsold X360 by 20k units this week. Chances are that it will outsell X360 by 20k units next week. Masterb8tr's method would have the PS3 outsell the X360 by 21k the next week, then 22k the following week, etc....
A better method, yet still simplified, would be to take an average weekly sales difference for the past several weeks or even months so that shipment fluctuations and software releases trends can be factored into the equation.
In fact, I'll work on that tomorrow. I bet you we still come up closer to 123-125 weeks than 66.
