Closing the Gap
                                          We may run into two gaps when we gather past figures.
                                          First, some figures may be missing. Second, two sources may
                                  disagree. Maybe accounting says we spent a certain amount on sup-

                                  plies and our records show a different number. When we find these
                                  gaps, we should try to understand the reasons. If we can get detailed
                                  line items to compare, that makes it much easier because we can drill

                                  down and find the differences.
                                    When numbers are simply missing, we may be able to do some cal-
                                  culations. We might have a total figure for the budget (possibly on the
                                  corporate financial statement or tax returns), so we can subtract the
                                  figures we do have for some categories and what remains is the
                                  amount of money spent on the unknown categories.

                                    Once we have our past figures, we should lay them out in a
                                 spreadsheet and create a new column (or columns) for our new
                                 estimates, as we did in Chapter 1.
                                 Using Estimated Figures
                                 If we can’t find actual figures, and even if we can, it’s good to
                                 have the estimates for the prior months or years. If we don’t
                                 have past actual figures, then this is likely to be the best we can
                                 get. And if we do have past actual figures, then the estimates
                                 can still be useful in two ways.
                                    First, we can set up a very convenient spreadsheet that
                                 shows past estimated figures and past actual figures, then add a
                                 new column for our estimates for the next period.
                                    Second, we may find that there are budgetary assumptions
                                 that we or the previous manager wrote. We can use those
                                 assumptions or adjust them based on what we’ve learned since
                                 they were made. Sometimes, the budgetary assumptions may
                                 tell us where to find the missing actual figures.
                                    If all we have are estimates, then we should think about set-
                                 ting them aside and starting from scratch. Remember, we have
                                 no way of knowing if the estimates reflect what was actually
                                 earned or spent in the past period.
