The CCC system assumes a base mechanical static advance of 20° with no computer advance/retard applied. If you set it to this with the CCC system connected (and in the right mode for setting the base timing), you will then have factory timing when you put the computer back into operational mode. With that said, the computer has no idea what you have the static timing set to. This means you can set the static timing to 22° or 23° (or more) and have a bump in a few degrees across the entire operational RPM/load range. That guy in the vid is talking about old school stuff (and I would NOT listen/heed anything he says).
