How to Get the Most From Cooperative Databases

Similarly, this technique can be used to optimize the performance of marginal lists by suppressing the weakest segments — those that perform just below acceptable response. Using this technique typically suppresses 10 percent to 15 percent of a list, thus providing enough of a lift to make a marginal list profitable or to help weaker segments achieve breakeven. Usually the lift in response more than justifies the incremental cost of optimization.
