Claim One:
1. A computer-implemented method for automatically adjusting a particular inflection point function, the method comprising: receiving a plurality of input time series, wherein each input time series of the plurality of input time series (a) represents a review rate and (b) corresponds to a different inflection point in the particular inflection point function; wherein the review rate of each input time series of the plurality of input time series indicates a percentage of a plurality of electronic commerce transactions that are associated with a particular score or higher; for each time series input of the plurality of input time series: proportional logic generating a trend review rate output; integral logic generating an integral delta output; derivative logic generating a derivative delta output; based at least in part on the trend review rate output, the integral delta output, and the derivative delta output, a controller generating a new inflection point value for the inflection point that corresponds to said each input time series; the controller adjusting the particular inflection point function based on each of the new inflection point values to generate an updated inflection point function; receiving a raw score that represents a fraud risk of a particular electronic commerce transaction; and generating and storing a final score for the particular electronic commerce transaction based at least in part on the raw score and the updated inflection point function.
