Sure - I'll send it to you as a geopackage file.

Hi Nyall,

Thanks for the explanations. I should have read the explanations of the help 
text more closely. It explains it all.

However, there still seem to be issues. Consider the following results below. 
First column is the result of $area, second column is area($geometry).

Sometimes the results are very close, in other cases the difference is massive. 
Like in the very first row. 32'087 vs 190'605'589 square meters. This can't be 
explained with ellipsoidical vs. planimetric. In this first row, the result of 
area($geometry) (planimetric) seems correct, while the ellipsoidical result 
($area) is massively wrong.

How can this huge difference be explained?

Can you share your dataset?

Nyall
