    What if the 'Declining' Column contains only negative numbers (e.g -5, -13, -2)? Will the EVwoPI be calculated taking the lowest number still, or the lowest number will be discarded in this case as all her zero (no profits)?

    • @joshemman
      @joshemman  5 років тому

      Having all negative values in a column should not affect the process here, unless you're dealing with costs. However, I don't understand what you mean by "taking the lowest number."
