The BS_Rand_Override interval at a new C-BSR might not be large enough (and
thereby contained within the 60 second BS_Period window at E-BSR) to prevent
the C-BSR from transitioning to E-BSR from P-BSR state and sending out an
empty BSM. In this case, the E-BSR will send out a BSM (if the new C-BSR is
inferior) without waiting for BS_Min_Interval.
Even if throttling is not required in above case, I feel that the MUST
statement in the spec should be modified to explicitly exclude "No Forward"
BSMs and Unicast BSMs from BS_Min_Interval limit to prevent a
misunderstanding as evident in earlier mail from Sumanta.
