I think you're right, dialing in yellow is probably enough.

It might be useful in case you run out of f/stops on your enlarging lens and you need a little time to burn and dodge.

I am always using f/11 and f/22. I don't even know if they are optimum, I am just forced to use those f/stops. (Not with the CLS35, don't know the times I would get from that).
