Water Temp Calculation using Friction Factor
I've seen various sources that are using the following calculation to find the optimal water temperature:
Base Temp (DDT x 3 (or 4 in a preferment is used)) - Room Temp - Flour Temp - Preferment Temp (if used) - Friction Factor = Water Temp
My question is, do we need to take into account the amount of each factor being used? It seems strange that percentages aren't taken into account.
