The size is controlled by the wind-driven polar vortex which has nothing to do with CFCs. The depletion of ozone is supposedly the result of reactions in ultra-cold stratospheric clouds. When the polar vortex breaks up, ozone quickly returns to ~300 Dobson units, with no net loss. It’s always a seasonal event.
