For several years the genetic genealogy community has asked for adjustments to the matching thresholds in the Family Finder autosomal test. After months of research and testing, we have implemented some exciting changes effective very soon.
● Minimum 20 total shared centiMorgans
Some people believed those thresholds to be too restrictive, and through the years requested changes that would loosen those restrictions.
Soon, the following changes will have been implemented to the matching program.
● No minimum shared centiMorgans, but if the cM total is less than 20, at least one segment must be 9 cM or longer.
● If the longest block of shared DNA is greater than 9 cM, the match will show regardless of total shared cM or the number of matching segments.
The entire existing database has been rerun using the new matching criteria, and all new matches have been calculated with the new thresholds.
Most people will see only minor changes in their matches, mostly in the speculative range. They may lose some matches but gain others.
