I'm not 100% sure, but through anecdotal experience and from what I've read (although haven't vetted), we lose track of counters at ~8 of them. That is, III is easily discernable as 3 'I's, but take IIIIIIIII, and try to recognize how many 'I's are there immediately.
- tathougies 9y agoThat's why you group five I's into a V?
- lou1306 9y agoThis, and another theory states that V is kind of similar to an open hand, i.e. five fingers, making it a convenient abbreviation. Consequently, X is just two V's joined at the vertex.
- saghm 9y ago> we lose track of counters at ~8 of them I must be below average in that regard; I never have trouble being able to distinguish the number of things when there are three or fewer, but it's somewhat difficult for me to tell four and five apart, and I essentially have to resort to manually counting for five and six.
