You can also combine the above three formulas into one formula. The syntax is:
100 * ((Sum (If (C> Ref (C, -1), (V-Ref (C, -1)), 0), 14)) - (Sum (If (C, <, REF ( C, -1), (REF (C, -1)-C), 0), 14))) / ((Sum (If (C> Ref (C, -1), (V-Ref (C , -1)), 0), 14) + (Sum (If (C, <, REF (C, -1), (REF (C, -1)-C), 0), 14))))
