Weak compared to what?

In my experience litigating medicolegal causation, this is the nature of epidemiology.

Like, the standard isn't "beyond a reasonable doubt," in my view, it's "preponderance of the evidence," aka "more likely than not."

More likely than not, the excess deaths were COVID. It's like when the weather forecasts a 20% chance of rain. Weak, right? No. It's a 100% chance of rain in 20% of the forecast area.
