extending back one-half (1/2) of the time elapsed since the date of the

gas delivered through the period such meter is out of service or out of

repair shall be estimated and agreed upon by the Transporter and

Receiving Party upon the basis of the best data available using the

first of the following methods which is feasible:


(a) by using the registration of the other party's check meter if

installed and accurately registering; or


(b) by correcting the error if the percentage of error is

ascertainable by calibration, test or mathematical calculation; or
