This is the smallest single broadcast-packet delta sample recorded within the interval this historical row represents. It matters on an archived historical sample row of that same receive-counter set, kept purely for trending past intervals rather than showing the current live value because a low minimum alongside a high maximum confirms the elevated broadcast traffic in that interval was bursty rather than continuous. broadcastPacketsDeltaMin at 50 next to a max of 15,000 in the same row on the endpoint this history row belongs to shows the broadcast flood came and went rather than persisting for the full interval.
