A bearing assembly comprising a housing and a ball at least partially housed within the housing. Firstly, a corrective mechanism enables a method for performing accurate integer divisions to be derived from an approximate division method which does not, of itself, always produce an accurate result but for which the range of errors is known. Therefore, PeaCoCk lends itself to reliable, robust predictive analytics based on purchase-behavior. In one embodiment, using the first opcode in the transition frame includes using the first opcode to determine that the transition frame is associated with the static initializer.
