Since there is no ozone hole at either pole about half the year, the answer is "Zero". Beyond this, we have only ~20 years worth of data, new and improved methods of determining the size of the hole, and shifting definitions of what is an "ozone hole". But for the most part, the smallest holes were the oldest recorded ones.
