This isn't true.
The three components of the current BCS formula are the Harris Poll, Coaches Poll, and an average of six computerized ranking systems. Each of these three components comprises one third of a team's total score in the BCS standings. These components are all known entities and may be simulated, regardless of knowledge of exact implementation. For example, the means of computation for a team's score in the Sagarin rating, which is one component of the computer average, is not public knowledge, but exact knowledge of the Sagarin rating isn't needed to attempt to create a reasonable representation of the total computer average portion of the BCS formula.
In contrast, there are absolutely no specifics as to how team selection will take place for the college football playoff. Any attempt to simulate it at this juncture will have no basis in reality.
