The Modeller does not calculate for calculating. It calculates for a decision.
You can XLOOKUP both ways, percent change, scenario manager, data tables, three pocket-money stories, linking sheets Prehled and a model audit. That is the skeleton of a table that answers “what if” without a pencil.
Today a final check of the model and preparation for the dashboard.
