Comment (by neteler):

 With that patch, the result of the precip vector map interpolation is now:

 {{{
 r.univar precip_30ynormals_surf
  100%
 total null and non-null cells: 54144
 total null cells: 0

 Of the non-null cells:
 ----------------------
 n: 54144
 minimum: 1133.44
 maximum: 1858.02
 range: 724.578
 mean: 1338.21
 mean of absolute values: 1338.21
 standard deviation: 153.479
 variance: 23555.8
 variation coefficient: 11.469 %
 sum: 72456125.5301044583
 }}}

 which has a reasonable range. Artefacts are visible but that will require
 parameter tuning.
