Before you use the answer
Write the batch size and measurement basis beside the formula before scaling. A weight ratio is not a volume ratio, and a flour-based percentage is not a share of total dough. Record the finished yield so the next batch can be planned from your own measurements.
A starter's hydration is water relative to flour, not water relative to total starter weight.

Why might a result be approximate?
Measurement uncertainty, ideal-model assumptions and floating-point rounding can all matter. Displaying more digits does not improve the original measurement.
