It's nice to use a scale, I suppose, when first starting out with your ( @JoNorvelleWalker ) new coffee adventures...you know, to set some parameters. ( I always use it to weight the beans, however).
For me, I figure that after 40 or 50 years of making pour over coffees, I can do without. And I don't need a timer, either. And no one is any the wiser.
