... increase the low_error factor (0.5 seems a sane value)...

... and set nearest_count to "20,10" or something alike, to make use of

Recently an error has been reported in 3.70RC3 causing noticeable
splotches when using only very few pretrace steps with a high
pretrace_end setting; maybe that's related to what we're seeing here.
