A method of optimizing the delivery of a set of data elements from a first device to a second device. The method includes retrieving from a data source the set of data elements, including a first subset of the set of data elements, a second subset of the set of data elements, and a third subset of the set of data elements. The method also includes transferring the first subset of the set of data elements to the second device. The method further includes selecting a forth subset of the set of data elements, wherein the forth subset can be comprised of data elements from the first subset and the second subset; or wherein the forth subset can be comprised of data elements from the second subset and the third subset. The method also includes transferring a forth subset of the set of data elements to the second device.
