Where Method I yields the greater amount of reduction initially, it will continue
to do so for subsequent RIB rates unless an ARF is given. This is so because under
the 1977 amendments, for initial entitlements after December 1977, the original reduction
factor is applied to all subsequent PIAs. Therefore, when Method I applies, it will
not be necessary to compare Method II results for subsequent RIB rates except as noted
in the case of an ARF on the RIB.
