I'd be happy to give it a try, if you tell me what the numbers mean, i.e. the "headings" for the columns, and how to compare myself to them. I've never looked at it before.

As I'd heard, he doesn't bother to include an Emilian source; almost as if he doesn't want to make it easy for me, as if I would ever use his tool.
Does he even bother to list the sources for these populations, the data for each individual?
If it's true, as I've also heard, that he only has one source for Liguria, and that one is from Genova, then I wouldn't expect a really close relationship to Toscana, although not a really distant one either.
You know what it's like in Italy. The genetics can be different in different parts of the same province politically. That's how much variation there is in Italy. The greater area around La Spezia was always part of the Lunigiana. Only relatively late in history did the Genovese take it over. That's reflected in the language. Some linguists in La Spezia hold that "Spezzino" and Sarzanese, and the "dialect" spoken in Lerici are not precisely "Ligurian", but rather "languages of transition". Spezzino has been described, if I remember it correctly, as "Emiliano un po' ligurizatto". Lunigianese itself is a "dialect" or" language" of transition, Emiliano influenced by Toscano and Reggiano/Modenese as parts of it changed hands numerous times over history and also by Ligurian by influences from the coastal areas. So, you have a situation where the further north you go in the Lunigiana the more Emilian the dialect, west of the Magra River and down near Sarzana and the border with "political" Liguria, themore Ligurian influence, and east of the Magra and into the Apuan Alps, the more Tuscan the influence.
The people are equally mixed and it started far earlier in time than even the genetics of the grandparents of the Spezzini would show. The surnames reflect it all. Many of the ones in eastern Liguria are found as or more frequently in Emilia and northwestern Toscana than in, say, Savona.
I guess that's a long way of saying that I know the people from these areas might not be "really" close to, say, a sample from Genova, or a sample from Parma, or a sample from Siena, much less a person with ancestry from all three parts of the larger area, but some calculators do seem to do a better job them others.
This sort of explains what I'm talking about, and why I don't quite "fit" the standard references, given I have two Emilian grandparents (but from the Appennino Tosco-Emiliano), one from the hinterland of La Spezia (but still technically Liguria, and west of the Magra), and one from the "middle" Lunigiana.

Too much information, but I know you'll "get" it.
