Ngaso sonke isikhathi khumbula ukuhlala unolwazi lwakamuva mayelana nezinqubo ezingcono kakhulu nezixazululo ezitholakalayo emkhakheni wokuphathwa kwedatha futhi, ikakhulukazi, ngokuhlobene namafayela e-DRR. Kulapho kuphela lapho uyokwazi khona ukusebenzisa ngokugcwele leli thuluzi elinamandla futhi ufinyelele ulwazi olunembile noluthembekile oludingayo ukuze wenze izinqumo unolwazi.
