Update to the Shared cM Project

It's here from Blaine Bettinger — version 4.0. He writes:

There are many changes to the minimum, average, and maximum values for relationships in Version 4.0 of the Shared cM Project relative to the prior Version 3.0. As the number of submissions for a relationship grows, the distribution of cM values for that relationship is more clearly defined. This allows for improved definition and elimination of outliers for each relationship. In some cases, the very large increase in submissions moved the minimum and/or maximum values further outward for a broader distribution in this version, and in other cases it moved the minimum and/or maximum values inward for a tighter distribution in this version.

Jonny Perl has updated the Shared cM Project tool at DNA Painter with the new data. Read his blog post here with even more information: https://dnapainter.com/blog/introducing-the-updated-shared-cm-tool/.

Thank you Blaine, Jonny and all those who contributed data.
