I have a physicist friend whose specialty for a number of years was observations from Antartica. He said that his evidence showed no sign of growth in the ozone hole.
Another friend who oversees grants said that only scientists who believe in a growing ozone hole are now awarded any grant money to study it.
So, I suspect that this is probably a one-time event that has nothing to do with growth in the hole. As we all know, weather and atmospheric phenomena don't obey handy little charts. They are unpredictable, at least by present knowledge.

That probably depends on what kind of data he has. The lowest concentrations don't go any lower, but the area of decreased ozone concentration is what is assessed in terms of ozone hole "growth" or "shrinkage".
Look up F. Sherwood Rowland and his buddy, Mario Molina; they have gotten quite rich since their initial clamorings brought all this on.
I will say that industry has adjusted quite well to the changeover to alternative refrigerants and I suppose there is no reason why even scientists shouldn't engage in a bit of self-promotion now and then.
