Did some search inside the pricing cvs and had the strange behavior that it seems not to be correct when variants are used.
For a product which uses a variant for a specific material I found this in the cvs:
{25,Black Strong & Flexible,not-for-sale,Never Printed}
{122,Black Hi-Def Acrylate,for-sale,Never Printed}
{6,White Strong & Flexible,not-for-sale,Never Printed}
The "Black Hi-Def Acrylate" is for sale in this product but uses a different model for the 3d mesh.
If I now want to change pricing for this material I assume that I can't do that via upload since the affected line does not represent the data of the Acrylate material.
I assume that this is a relict from the times when model and product where identical?
