I do agree though about not all wire being equal. The larger stuff I've seen listed as 4 awg and held has not been OFC or bare copper though, it's been CCA - it's lighter but it doesn't conduct as well based on the measurements I've seen and what I've read.
I think your references and Nate's are both great for teams to have access to and understand. Just helping to provide more information for people to leverage.
