Hi dave13
You can choose the variable for highest quantity as well but in that case there will be two scenarios.
Suppose you choose rate of Pump1 as x then Pump 2=x/2 & pump3=x/4. now as you can see the variable are in fraction and its generally easy to work with whole numbers than fractions.
so if you are starting with highest number, then use smart variable. let rate of pump1 be 4x, then pump 2=2x and pump3=x (essentially this is same as saying let rate of pump3=x)
