I'm with the above on longevity vs. ingredients. If you introduce less stable items like cooked drippings you will shorten the shelf life of the product. How long? I don't know. If I use bacon fat I would use the same rule I use for the cooked bacon. When it goes. the associated products should go. Simple sauces like the No. 5 should store longer as the ingredients are fairly neutral in singularity and don't have significant affect when mixed.
I guess my opinion is, go with your gut, but not literally.
