We address the statistical implications of absence of preferred scale ratio in stochastic extended systems. We identify in this case the only possible functions governing the scaling exponents of structure functions. This enables us to determine the nature of intermittency when no scale ratio is privileged, to clarify the conditions relevant to this regime and to reveal hidden preferred scale ratio in various works of literature.
