Is there any limit @1500 relatives only?
New ones keep popping yet counter's set in stone at 1500.

Here is mine:
I feel like this breakdown makes sense, the Iranian, Caucasian, & Mesopotamian, is excess CHG/IN.
Not bad considering the V5 chip only reads about 30% of the genotype coverage. As per uploading it and seeing the results on Admixture studio 2.5.
At any rate, the Ancestry chip is much better, it covers about 90%, and there is indeed a stark difference.
It would be interesting to see what the 23andme algorithm would give me with my Superkit raw data, which coverages about 95%.
The more samples they get from Italy, the higher this will go.
The 4% Sardinian doesn't surprise me. I always come up with high scores for settlements in Old Europe, i.e. Copper to Early Bronze Age "natives". It draws me "south". Sardinian boats make the run to La Spezia constantly, so, as I said, no surprise.
Neither is Provence-Cote d'Azur a surprise. I'm a quarter Ligurian, after all. Not much difference genetically on either side of that rather recent political border. Heck, Garibaldi was born on the other side of it, and tons of the last names there are Italian.
How they don't classify that and the southwest of France as "Southern European" is beyond me.
So, I think that 10% and 4% should be added to my "Italian" total. :)
I apparently have more of my father in me than my mother, however, which doesn't at all surprise me, either. I may look more like her, but I'm definitely my father's daughter in mostly everything else.

Ancestry Composition was updated to 5.9 only for chip v5 so far. I tested v4, for example, and I'm still at 5.2 (from abt. one year ago).
Comparison with Ancestry:
Northern Italy85%
France11%
Spain4%
I like their timeline feature. This is the earliest: 1750.
I just had a strange match show up. She's only a 5th-8th cousin match, but surname from around Carrara, so definitely a relative on my mother's side. She looks more like me than my own brother, more than anyone except my mother. Even my first cousins on my mother's side don't look as much like me.
I suppose then it's a "Tuscan" look, while my brother looks completely Emilian.
Genes are really weird; a complete crap shoot.

Do anybody knows how to interpret the Trace Ancestry in terms of Chronology?
I wouldn't interpret it at all, because even the larger percentages are sometimes unsure, especially if its two related ancestral components, but trace ancestry is totally speculative. It could be true, however, if you find matches which prove it. In such a case, you can calculate it like usually, based on the segment(s) length. Usually its just one or two segments, so you can search for a match with which you share it. If there is none, I would forget it. If there are some, I would try to work on it based on the match in question.
How much trace ancestry do you have in mind? Percentage or cM, number of segments?
86,8% Eastern European,
9,1% Greek and Balkan,
0,3% Spanish and Portuguese,
1,2% Western Asian,
0,7% Ashkenazi Jewish,
1,4% Broadly Southern European,
0,5% Broadly European
My southern european ancestry passed from 8,9% ( 2% Spanish&Portuguese / 0.9% Italian ) to only 3,7% with 3.1% of it being Italian.
Edit and disregard.

Its not possible for two reason: First the trace ancestry is usually speculative and might be in many cases just noise or an artefact of the algorithm. Secondly, if its really just one small to moderate size segment, they can persist for many, many generations or being the result of a fairly recent admixture event. You can't tell apart, unless you have relatives tested which get the same segments plus additional ones. Then you might be able to conclude its more recent and was just sliced in half in the last generation. Otherwise you can't distinguish fairly old from fairly recent.
A lot of my excess Balkan which I got now is close to "broadly European" undefined segments. So I guess the algorithm just smoothed it out by taking what's there and assigning the bordering segments to the same ancestral component, because of a lack of a better reference. That way creating excess minority ancestry on just a few chromosomes on which this minority ancestry dominant.
Its very telling that better defined ancestral components, which are more clearly separated, don't do that. G & F, EE and Balkan have clearly some overlap. Same applies to Italian, G & F and Iberian too, as I read. Even more so British and F & G of course. So by changing the algorithm to smoothing out, many minor ancestries will be lost on some chromosomes or the whole genome, whereas being blown up for others. But there was little choice for 23andme, they really should work on improving their references, their algorithm seems fine.
Their references are primarily their customers. The major reason mine changed is probably because they got more customers from Emilia and so they were able to narrow it down.
They're not trying to do anthropology; they're trying to get samples for medical research they can sell. The by-product is a sort of genealogy, which in cases like mine, where I know where the vast majority of my ancestors have been for at least the last five or six hundred years, proves it can be remarkably accurate.
