With HD=0.94 and an allocation of /32 the threshold would be about
50%.  You would have about 32,000 customer assignments left at that
point.  Lead time should not be an issue.

The threshold appplies to total number of /48's.  The choice of dense or
sparse assignment policy does not affect the threshold.
