My apology if this has already been answered (I searched through the posts and did not find a clear answer).

I am just curious about peoples' opinions/impressions about the accuracy of one test over the other. The reason I ask is because my results do vary for each "service", although they do share a few groups in common.

My 23andME results are:
57% Ashkenazi
22% Eastern European
1.8% French/German
.1% Finnish
4% Broadly Northwestern European 4.0%
2.6% Balkan
1.3% Broadly Southern European
11.6% Broadly European
.1% Yakut
.1% Sub-Saharan African
.1% Unassigned

FTDNA:
51% Ashkenazi
6% Middle Eastern (3% NW Africa (Morocco/Tunisia), 3% Levant)
2% Scandanavian
41% Eastern European

From what I have read, 23andMe's ancestry composition profile supposedly reflects one's ancestral composition within the last 500 years while, it is my impression that, GEDmatch tests deeper ancestry. If the GEDmatch calculators reflect deeper ancestry, how far are we talking about? 2000 years ago? Is there a reference table for definitive time periods per test (Eurogenes, Dodecad, MDLP, etc.)? When Eurogenes V2 K15 spits out North_Sea %15.08/Atlantic %11.66, is that 1000 years ago, 2000 years ago, more?

Specifically vis-a-vis FTDNA and 23andMe, if, from what I have been told, the Family Finder test and 23andMe cover about the same period, about 500 years, why would FTDNA find a specific and substantial amount (6%) of NW African and Levant ancestry while missing the NW European ancestry that 23andMe estimated and, conversely, why would 23andMe come up with 0% Middle Eastern ancestry while being able to pinpoint .1% Yakut (even when set on the "conservative" end of the spectrum) and .1Finnish% ?

Any thoughts would be greatly appreciated =)

For me, 23 and me is more than 2000 years and gedmatch calculators, a mix of very old (over 5000 years) and most recent (less than 2000 years). It depends on the components.
For example Atlantic and North-Sea, are components that are predominantly found in these regions today, but that does not mean they originate.
Tooday, Eastern Europeans also have these components, it does not mean that western Europeans migrated to the East, but Europeans Western and Eastern Europeans have ancestors in common in ancient times.

The results of gedmatch calculators are difficult to understand!
It is imperative to compare the results with the country averages, for not doing false extrapolation.

Can Gedmatch calculators really be relied upon since most only cover between 90,000 and 140,000 SNPs against 577,000 SNPs at 23andMe.

Interesting results
