1. A computer-implemented method for calculating at one or more processors a delta value representing a change between a first value for a consumer data element and a second value for the consumer data element, comprising the steps of: a. receiving from a computer-readable medium in communication with the one or more processors the first value of the consumer data element and the second value of the consumer data element; b. calculating at the one or more processors a first difference between the second value and the first value of the consumer data element; c. calculating at the one or more processors a ratio between (i) an absolute value of a smaller value, wherein the smaller value is a lesser of the first value of the consumer data element and the second value of the consumer data element, and (ii) an absolute value of a larger value, wherein the larger value is a greater of the first value of the consumer data element and the second value of the consumer data element; d. multiplying at the one or more processors the ratio of step (c) by an asymptote to create a compression value for the consumer data element; and e. adding at the one or more processors the first difference between the second value and the first value of the consumer data element calculated at step (b) to the compression value for the consumer data element calculated at step (d) to create the delta value for the consumer data element.
