Hi Paul,
It's not a problem of the data, since either way a normal points, the data is valid. It's just what we interpret visually, and that's a whole different story ( see posts above ).
In general, yes, you should ask the data provider if they have methods to provide data with 'better' normals. But I assume they won't be able to provide data that needs no manual rework.
