No, you never showed that 3 parts per BILLION of CFC's can somehow overwhelm O3, while the dominant cause of the annual breakdown are from these which I have already quoted, which you completely ignored:
bolding mine
N2 amount to at least 780 parts per MILLION, the others a lot more than CFC's yet somehow gets ignored in favor of a trace amount of CFC's which at its PEAK reached 3 parts per BILLION, which was about 18 years ago. Yet when there were near ZERO level of CFC's in the air in the 1950's, Ozone "holes" were found to exist anyway, despite the elevated Solar radiation at the time.
Then you IGNORED that chart from NASA showing that CFC's doesn't have a measurable effect on total ozone changes since there is so little of it in the first place, which is the point you ignore.
Meanwhile this gets ignored all the time since it greatly weakens the already trivial effect CFC's ever has on O3 levels:

The Antarctic ozone depletion caused by Erebus volcano gas emissions
December 2015
Abstract
Heterogeneous chemical reactions releasing photochemically active molecular chlorine play a key role in Antarctic stratospheric ozone destruction, resulting in the Antarctic ozone hole. Hydrogen chloride (HCl) is one of the principal components in these reactions on the surfaces of polar stratospheric clouds (PSCs). PSCs form during polar nights at extremely low temperatures (lower than −78 °C) mainly on sulfuric acid (H2SO4) aerosols, acting as condensation nuclei and formed from sulfur dioxide (SO2). However, the cause of HCl and H2SO4 high concentrations in the Antarctic stratosphere, leading to considerable springtime ozone depletion, is still not clear. Based on the NCEP/NCAR reanalysis data over the last 35 years and by using the NOAA HYSPLIT trajectory model, we show that Erebus volcano gas emissions (including HCl and SO2) can reach the Antarctic stratosphere via high-latitude cyclones with the annual average probability P¯ann.'>P¯ann. of at least ∼0.235 (23.5%). Depending on Erebus activity, this corresponds to additional annual stratospheric HCl mass of 1.0–14.3 kilotons (kt) and SO2 mass of 1.4–19.7 kt. Thus, Erebus volcano is the natural and powerful source of additional stratospheric HCl and SO2, and hence, the cause of the Antarctic ozone depletion, together with man-made chlorofluorocarbons.

====================================================
The CFC's effect has always been overblown to the point of stupidity since the amount is at the PEAK was about 3 parts per BILLION (year 2000) versus the N2 alone is 780 parts per MILLION and then you have H2 and Cl that are also in parts per million.
This is why that skepticism has increased in recent years when more and more research shows that the Stratospheric conditions in the South Pole region coupled with a very high continentail elevation have existed for a long time to produce "holes" naturally.
