Apart from the record number of atoms, phases, parameters, citations etc used to describe just 3 broad peaks, I object to this kind of refinement being called "Rietveld refinement". Luca called it "Rietveld-like" in MAUD, which was used here, but even that is wrong. The term "Rietveld refinement" should be restricted to the refinement of crystallographic parameters - cell dimensions, atom coordinates etc. and not applied to quantitative analysis of phases, particle size etc. Fitting peaks in powder patterns was done before Rietveld, who must be turning in his grave to see his name associated with this kind of thing.
