Before revision:  In this bound, n-step Fibonacci sequences do emerge, and appear to set the fundamental laws that characterize the optimal operation of chunk-based systems . A further technical contribution of the paper is an advance in the theory of n-step Fibonacci sums for which a prior reference result was missing .
