"The prime sequence has no "memory""

If this were true, then we would see the Ramanujan primes ~ 3n instead of ~ 2n. http://arxiv.org/abs/1105.2249

The "memory" is in a way a type of "feedback" by the prior primes to the future gap, and is related to the number of Ramanujan primes, n. See the corollary at http://en.wikipedia.org/wiki/Ramanujan_prime and think about how these log N's add up between x/2 and x. Note also Generalized Ramanujan primes and how they relate. Also note, how sharp the range is between [p_k,2*p_(i-n)]. This is where p_i is found.
