Has death due to Covid-19 become less common? (smarky7cd.github.io)

It's an interesting graph. I would discard the first 25% of it because during that time there were no good CoViD-19 tests. If there had been, perhaps the Y axis would need to be extended...

The higher the number or line, the better the situation. Case / death ratio, which is usually reported the opposite way as CFR.

Not sure it answers less common, as I interpret as Covid deaths vs all deaths.

Something seems off when the longest moving average point is the most outlying point. One would expect the raw data to have such points.
