My best single plot (not 22-chr) would incorporate my merged data (over 1.15 million SNP), so I plot my merged Ancestry+23andMe results for K13, K15, and K36 against both IllustrativeDNA "official" Ancestry-only coords, then plot in the DNAGenics Ancestry, 23andME, and the AVERAGED G25. The averaged G25 looks most reasonable and closest to official, so I trust those 22-chromosome plots more than I do the Eurogenes of K13, K15, or K36.
Ancestry-only data plots me slightly more southern than 23andMe, so averaging them makes most sense. The average finds the middle point, which is roughly .0025(0.25%) off the "official" Ancestry-only.
Not everyone seems to get accurate DNAGenics coordinates, but mine plot basically on top of my IllustrativeDNA plot, so I trust they are more accurate than any individual K13, K15, or K36 resultant plots with 22-chromosomes. That said, the K36 single plot is closest to my best Averaged plot, so if I had to pick one for me as a single set of coords out of those 3, I would go with K36. The K13 22-chr plot looks better to me though than the K36 in relationship to what I consider my best set of 22-chromosomes. I can attach a pic to show how they individual plots relate and are shifted from each other. Give me a moment.
