Okla. Admin. Code § 165:35-25-19
Each utility shall maintain a program for identifying and analyzing its worst performing circuits during the course of each reporting year. The program shall include, but should not be limited to, an analysis of the top 5% worst performing circuits for the entire utility and for each of the utility's operating regions, if the utility is divided into regions, and the actions taken to improve their performance. The worst performing circuits shall be identified and ranked using the SAIDI and SAIFI (and to the maximum extent practicable, MAIFI) values computed for each circuit, and in any other manner chosen by the utility. The details and results of the ranking and program to improve the performance of these circuits shall be submitted as part of the annual reliability report described in 165:35-25-20.
