Before revision:  This positive feedback can drive large fluctuations in the internal state of URLanism away from its mean, resulting in long runs in favorable directions but short ones otherwise. In this new regime URLanism achieves a "ratchet-like" gradient climbing behavior unexpected from mean field theory, and drift speeds much faster than previously believed possible .
