Actually the ozone layer didn't recover. They just don't talk about it so you forget about it and assume everything is good and they were right about everything.
In 2006 and 2010 the largest holes to date have been observed. This after Ozone depleting chemical levels in the upper atmosphere had been declination since about 2000.
Not that 40 years worth of observation is relevant for something as complex as the upper atmosphere.
You need at least a 100 years just because of the factors we know about such as solar maximum and minimum, solar events or the lack there of, El Nino years, volcanoes, intense wild fire years and so on.

I agree, it's the sun.

I should also add that no elevated levels of UV were ever detected at human inhabited latitudes.
Then 80% of CFCs were released in the northern hemisphere but only caused a hole in the south? Mmmmhmmmm...
