%LVR = (%LVAVG1 - %LVAVG2 / %LVAVG1 * 100
where:
%LVR = Percent leaking valve reduction.
%LVAVG1 = (%VLi + %VLi = 1)/2.
%LVAVG2 = (%VLi = 1 + %VLi = 2)/2.
where:
%VLi, %VLi = 1, %VLi = 2 are percent leaking valves calculated for subsequent monitoring periods, i, i + 1, i + 2.
%RR = percent reduction required each quarter, as calculated according to § 63.168(e)
%VL = percent leaking valves, calculated according to § 63.168(e) , at the time elected to use provisions of § 63.168(d)(1)(ii)
