Compare for matching names in Column A and calulate variance on a match

Need Macro to Compare names in Column A and on a match calculate the variance of the other columns. The first greoup of names in cloumn A will always be a subset of the second group of names and the third group of names is exactly the same as the second group of names but the other columns for the third set of names will contain the delta between the matches, if there is no match then assume the delat as the full value associated with the second group. I've updated the sample spreadsheet. Thank You
