The culture grows during fermentation, so a smaller inoculation has more doublings ahead of it. The law is a 0.6 power, and it reproduces the landmarks every baker knows.

A preferment is not a split of flour and water. It is a fermentation with its own schedule, its own dose, and a ripe culture that then carries the final dough.

Preferment
A poolish or a biga ferments on its own first, with its dose and its hours. The engine computes where the culture stands before it is mixed in, and the final dough starts from there.
Six modes
You switch modes inside the same calculator and the engine recomputes the formula. No mode is reserved for a paid plan.
