Address how the model is dealing with floating point imprecision

[mkote]

The current model is implemented using the double datatype for arithmetic operations. However, this means that it is affected by the inherent imprecision of floating point arithmetic operations. In other words, the series of summations and multiplications will likely yield an imprecise final rating. This could be a potential problem for teams with very close ratings. Further, since this model is used to calculate the official valve rankings, it becomes hard to port the code to other languages, since floating point imprecision is not consistent across programming languages.
