Model complexity in ESB

I need to study the complexity of models in the PRECISE engineering shape benchmark (ESB) collection. Although such approximation is not always true, I considered that more complex objects contain more faces, while meshes with less triangles represent simpler models. Indeed, a simpler object might contain more faces than a more complex one, depending on the mesh. However, this is not common in the ESB collection and the face count is easy to estimate. From this estimation, I concluded that the majority of the models in this collection contain more than ten thousand polygons, as illustrated in chart below.
