Coin Delta

The Coin Delta is the difference in dollars between two consecutive polls. The calculation is used to determine if the recent daily earnings are drastically different than the Average per Day field, just below it. Large differences may indicate a problem with the payphone. Both the Coin Delta and the Average per Day fields use the communication history for data. The communication history is updated automatically with each poll or report. More money-critical figures produced by Panorama use Call Detail Records, which provide specific information about each call. See the topic View CDR for more information about this type of data.
