noun

Plural: misperfections

Imperfection by mistake or neglect; insufficient, erroneous or otherwise wrong precision; a misleading or uncertain result of intended perfection; misprecision.

Examples:

Back then, it was something similar to today's lazy people leaving out not only the first digit from the date, but they abrogate the whole century in one swing. I am sure you've already seen in everyday life the misperfection of some people writing only 79 instead of 1979. Or they scribble something like 12/10/11 and are supremely pleased with themselves for how rationalistic they are. They even cannot tell later if their own record meant 12th October, 10th December, 10th November, or some other combination. It's even harder to guess the year unless we know the exact context of the given entry. Was it the year 12, 112, 312, 1012, 1812, 1912? Or 511, 1611, 1711, 1811, or any of the unconsidered remaining deannuations.
