A pontos újbóli elosztás a további memória újbóli elosztását csak a meghatározott felső határig végzi.A memória felső határértékének átlépésekor az újraosztás során a titkosított adatokat a lehető legfeljebb a lemezre másolják.Amikor az elosztás során a lemez memóriájának felső határértékét meghaladja, a megfelelő kivételt eldobják.A teljesítménynek magasabbnak kell lennie, ha ezt az opciót kikapcsolják, mivel amennyiben lehetséges, nincs további másolás.Ez azonban a memóriára vagy a lemezre meghatározott felső határértékek átlépéséhez is vezethet.
