If these coordinates of modern Italians included in the updated DODECAD K12b spreadsheet were produced by the “Sizzi” that writes in link below, they must be disregarded.

The man is a racist. This is his conclusion of the "article" contained in the referred link:
“Le distanze genetiche delimitano popoli, etnie, subrazze e razze, alla faccia di chi continua a ripetere come un disco rotto che le razze non esistono. Pensate anche solo alla biodiversità italiana, dove il gruppo settentrionale è ben distinto sia da quello toscano e centrale che da quello meridionale, soprattutto. Quanto basta per poter parlare di gruppi etnici differenti. Figuratevi se dovessimo parlare di gruppi razziali.”
Racists are sick people who should not be given credibility or a platform to spread their absurd ideas.
Believing that dna gives us the ability to distinguish people of different "races" or what are now called breeding populations doesn't make you a racist, imo. That's what we're doing every day. Are we all racists then? From the little I know of him I think the term might fit, but not for that reason.
In terms of the samples, when dealing with the work product of anyone with an obvious agenda, it behooves one to be cautious because of the possibility that this bias would lead to distortion of the data. That has been the cause of my hesitancy about some of Eurogenes' results. When it's academic samples and there's some degree of transparency there's less concern.
I don't know the source of those samples, so that's one area of concern; the other concern is whether someone like this is to be trusted choosing samples, if it is indeed his work.
I'm going to go back to using the original Dodecad.
For example, these are my closest Medieval matches:

The fits aren't as good using the updated samples, and they don't make as much sense to me for samples all from Rome.
Only problem, of course, is that the original dodecad is missing samples from certain areas.
