Notability is sort of a bad metric since it’s incredibly subjective. And we’re not just worried about extraneous inclusions in 2021, we’re also concerned about missing data points for previous years - there’s no real statistical correction for “my inputs are biased in unknown ways”. You need to do real analyses with better quality data (i.e., national death registries) to find a ground truth to compare to. But good news, since this is quite a hot topic I’d expect that people are already looking into that.
