If this data is from PDF set 22 it would have been added around 1972 - which is hardly the 21st century - so I would think DeWolff should have stopped turning in his grave by now! However, your point was still quite valid even in the dark ages of the 20th century. The ICDD clearly needs to critically review past data sets to cull the inaccurate (and also the redundant) entries.
