3rd party sites-recommendations/how do they work etc.

[Boudicca]

Hi,
I've seen many different 3rd party sites mentioned here and elsewhere that you can use to explore your FTDNA autosomal data. I understand how to read some (I think) but others leave me perplexed!
I've had a go with the Gedmatch Dodecad/Eurogenes admixture tools but they seem to give different scores for what appear to be essentially the same groups eg Baltic/Eastern European I get 3% South Baltic with Eurogenes but then 14% Eastern European with Dodecad
I didn't know if one used more samples than the other, or one was ancient scores the other recent etc.
Any help would be gratefully received!
Thanks.

Differences most likely due to different naming conventions as there is a limited set of population references - everyone uses them. Are South Balts the stand-in for East Europeans, generally?
