None of the differences, either split by company or by twin seem egregious or even particularly unsatisfactory. They cite that AncestryDNA measured each of their DNA to be 99.6% similar, and really, that seems like the error rate you would about expect for the Ancestry results they got. They got the exact same regions and only a percentage point or two off in each region's share.
It's not like they're fully sequencing every DNA sample they get.
> AncestryDNA found the twins have predominantly Eastern European ancestry (38 per cent for Carly and 39 per cent for Charlsie). But the results from MyHeritage trace the majority of their ancestry to the Balkans (60.6 per cent for Carly and 60.7 per cent for Charlsie).
This part of the article especially seems like hair splitting considering the Balkans and Eastern Europe tend to have a lot of overlap. In fact, "Balkans" in particular is an extremely ambiguous linguistic term and can mean so many different things to so many people.
