I do have one final question about the group output sockets. In Kent's video the output sockets for Factor A & B are yellow (RGB values) but in the screenshot they are gray (Mathematical values). Just wondering why and/or if this has any impact on the node group?
Here is a link that might help.

You show the node group but not it's contents. :(
