Blaine Bettinger has released new autosomal DNA relationship statistics charts. It is so awesome that he is helping us all by collecting and analyzing this data. I first noticed the charts when checking out the newly updated ISOGG wiki page on autosomal DNA statistics.
Blaine Bettinger goes into more detail and has even more helpful charts in his blog post: August 2017 Update to the Shared cM Project. Check it out.
