I second Tom's approach. It's the one I use in my classes.
The instructions can be found in my course folder in Google Drive
<https://docs.google.com/document/d/1tLgXo2cEoo0uUm_W3r3-rJOWnMHkjjLsW4-D8c4BBA0/edit?usp=sharing>.
Look to the Peer Evaluation Final Instructions header toward the bottom.
Seems the best approach is to keep grade ratios within a group. That way
issues within one group, like the one discussed by Kristie, do not affect
other groups' scores.
