Correction - thinking about it I realized my use of the term multifractal here was incorrect, apologies, in fact a multifractal (where the resulting set is made less homogenous) would tend to increase the guttering problem. Summing/normalizing turbulences simply breaks up contiguous areas of pooling. My bad :P
