An expert workbook needs formulas that survive changes to the source. A copied range may miss an appended record, an OR test may count a row twice, and a top-N formula may discard someone tied at the cutoff. Treat the stated edge case as part of the result.
This review uses fresh fictional capacity, activity and scoring data. Choose any formula that follows the requested rule and continues to use the source cells. For spill tasks, keep the output area clear. For a cumulative calculation, decide which end of the range must stay fixed. The last task returns a dashboard leader from the calculated regional results, so the label changes with the amounts rather than staying typed into the report.
