How does FTDNA determine the ICW status? In order for FTDNA to calculate the ICW status of an individual there must be an algorithm to evaluate the at-DNA results for that individual against some criteria based on the at-DNA results from the base pair. Has anybody been successful in back-engineering or divining the logic used for this comparison? A related question; what does the ICW "X status" actually tell us? I have seen a statement implying that it means that these individuals are "blood relatives". That would be great but seems a little too far reaching. Puzzled!

Jim The ICW algorithm does not include arDNA. It does not include genealogy. It only matches names between your Match list and someone else's Match list.

Jim How does this compare to AncestryDNA "shared matches" that DNAgedcom downloads as ICW ?
