Please take a look at our C2 Matrix Eval Lab so that testing can be performed in a consistent manner. The easiest way to contribute is to copy the row you want to update from the Google Sheet Golden Source and share it with us via Twitter or Feedback form.
You can also let us know if there is a particular field that is not accurate such as "Baby Shark row 5 states implementation is by pip3 but it is really install.sh" (this is just an example). We do prefer the entire row filled out.
