Yeah but isn't the absolute measure the one that matters? Because the ozone is blocking UV radiation, and it's the absolute amount of ozone that determines how much radiation is blocked, not the relative amount of ozone in one area vs another.

At best, the relative measure might act as an early warning of a problem. But it could also just be turbulence in a chaotic system. So it's harder to decide if it matters or not.
