I have a column of numbers (column A), a sample of which is below. &nbsp;What I need a to calculate in a single cell &nbsp;(B1) is the largest percentage drop from any given value to the lowest subsequent value. &nbsp;I can easily do this using another column to calculate the percentage drop, but I want to do it within one cell. &nbsp;I want to use Small so I can cput the second largest drop in cell B2, etc. &nbsp;Is this possible?<br />
