Yeah it's probably not so rare. The errors in this case never fall on the side of false positive, and it's impossible they caught every breakthrough case. It follows that there are more breakthrough cases than what's reported. The point of contention is by what margin the CDC is off.

If you really want to embiggen the problem, ask yourself how many people got covid but never got tested. The rate of mild infection is probably a lot higher than reported because only people with anxiety and/or serious covid bothered to get tested or hospitalized. Everyone else called in sick or didn't know/care.
