Grind size/ratio adjustments for small dose pour overs?
(midwest.social)
The Oromo people would customarily plant a coffee tree on the graves of powerful sorcerers. They believed that the first coffee bush sprang up from the tears that the god of heaven shed over the corpse of a dead sorcerer.
As with just about all things coffee, James Hoffmann is a good starting point.

This should help dial in your grind size to reach a target brew time. Trial and error (with notes!) I'd half the fun to figure out your recipe. At the point my ratio/grind is pretty scalable for small and large pours.
