to add to the comment about SS being hard and therefore requiring more honing time. Isn't carbon steel generally "softer" and easier to put an edge on than Stainless?
If my memory is correct, then that would make using the same honing routine for both steels a recipe for 50% success at best. I would use a minimum circle/stroke benchmark on a bevel setting stone for any type of razor, but only as a reference for when to start checking if the bevel is fully set. Then continue on as each individual razor requires.
