You may notice that numbers seem to shift from month to month. For example, something that said 1,000 sales for a January report might say 1,023 sales for January in a February update. This is because InfoSparks is constantly "updating history." 

Instead of freezing the data and reporting only that number at a single given point in time, it is refreshed on a regular basis, reporting the most current numbers available in the MLS. This accounts for the reality of an ever-changing market and catches important edits to previously accounted for data. (For example, a sale will be removed if the deal collapses.)
