Whatever inputs are required for a particular calculation there will exist the optimum at-source location for all the ingredients. In other words, whether the ingredients are raw inputs or other calculations, for each one there will be a single best location source.

At-source referencing means collecting inputs for a calculation from the correct place of first calculation or input rather than from any other location in the model. The overall picture of the references in the model is one where there are no daisy-chains.
