This value assignment ignores dialect differences. Some dialects/speakers can have /-ks/ in basic vocabulary, though for other speakers this cluster is broken up with an epenthetic vowel, e.g. nekis ('next'). Also the increasing use of English plural /-s, -z/ in town Bislama means there's some variation between Value 2 and 3.
