Some News on Ancestry's Update of its AncestryDNA Matching Formula

We spotted some news regarding Ancestry's planned update of its AncestryDNA Matching formula. Some of it will now be done in stages with the main aspect of the change now taking place in late August rather than very shortly.

We reported on this planned update in a July 17, 2020, post. After explaining the planned changes in that post we covered the three ways to save small centimorgan matches from the planned tossing of the pool water and gave suggestions on what to do to find and review DNA Matches in the 6 cM to 8 cM range that may have value to you. See that blog post for details.

The stages of the AncestryDNA matching formulate update are now:

In the beginning of August, the rounding of the centimorgans shared that came with the last change in matching equations will go back to using/showing the decimal point so you can clearly see which matches are truly 8.0 cM or above and which are actually less than 8.0 cM and will be the ones to disappear with the newest matching equation.
 

In the middle of August, you will see the length of your longest shared centimorgan segment.
 

In late August, DNA matches must share 8.0 cM or higher so those less than that will disappear unless one of the three things mentioned our July 17th post have been done. And, yes, it has been clarified that starred matches count as a group.

If we hear of any other changes to the planned update we will let you know.

See you soon at Mt. Clemens Public Library! (Some day soon.!)
