I selected one polygon (one of the troublemakers, FID:10) from your
shapefile and created a new shapefile with only this polygon. Even with
only one polygon in the layer, you'll still get a label that's placed
incorrectly when using the Over Centroid option . You have two

No they are singlepart.

You are right about the possible placement of centroids outside the

Hi!
I don't know if I am right but .. isn't the placement of labels done
with it's own engine where you can tell if you want to have it right
above /left below () the point depending on available space?
Probably you switched on some of these possibilities and

I tried it with same result.
It seems that only smaller objects have the label way off. Most probably

Yes you can choose different sort of placement but I have selected Over
centroid which removes a lot of the other placement adjustment
possibilities.

When trying to label a polygon layer I wanted to place the label over the
polygon centroids.
This should be possible by selecting the ABC Advanced pane and ticking off
over centroid.
But it seems ABC is rather poor at calculating the centroids.

Hi,
In the image below I have used Vector/Geometry tools/Polygon Centroids/ to
add the polygon centroids and especially for some of the small polygons the
labels are far off (even though these polygons are very regular - they are
made as buffers around a line).
