Did it help? Next comparison:

Worked examples (illustrative, subject to equipment capacity):
Filter: 30 g coffee / 500 g brewing water = water:coffee ratio 16.7:1.
Espresso: 18 g coffee / 36 g drink = coffee:drink ratio 1:2.
Precision Brewer: 55 g coffee / 1.0 L brewing water = 55 g/L.
Water added and drink yield are different measurements. Keep units explicit.
Hold dose, water, filter and method constant when comparing grind.
Choose the recipe by repeatable taste; an elapsed time alone is insufficient.
