I recently learned of the "watchmaker's four", but I'm not sure I understand it: I'm sure that's worth every CHF of the asking price, but how does "IIII" balance an upsidedown eight?
I think it's just about having a similar size/proportion of marker, and to avoid having a numeral with a single 'I' which may confuse with the other indices.
