In general, the human mind does not grasp large numbers of items well. In human development studies, and actual experiments, the average human can quickly identify & conceptualize about 7 items. If more items are presented, it gets categorized as simply "a lot", or "many", rather than distinct items. Because of the frequency sorting, and "drill-down" selection of word candidates, 5 choices worked out best in the tradeoff between available word completion candidates, speed of typing, and finding the actual word that was desired (without pushing the maximum of 7). Note that if a large number of words are presented, the user is forced to read & recognize each word until they are find what they want - in WordComplete simply typing the next letter is quicker & more effective!
