How well do North Amerindian calculators work?

[CrazyDaisy]

On gedmatch there's some calculators that specifically calculate North Amerindian instead of central or south like most calculators. I tend to get lower scores like 24% on them. On one of them I even got 2%. Do you think they actually work?

Which calculators do you mean? I know that MDLP World-22 calculates three types of Amerindian.
