Part of explaining this "funny" coincidence is going to be how one motivates their selection cuts, like the choice to use only one database instead of crossmatching several for better robustness [1]. The choice to ignore higher ionisations, the choice to ignore any systematic effects from the fact that the heavier elements, with their shorter wavelengths, are just downright harder to work with experimentally.

Finally, what do our current best atomic models predict that this distribution should be? These authors seem to think nobody models atomic spectra...
