I'm skeptical of the source numbers here. The early dates on the X-axis were over 7-months ago. Full factor mortality adjusted tallies from early months don't seem to be included? I can find no mention of full-factor mortality adjustments on covidtracking.com. In other words, are the numbers verified and adjusted by other methods? Full-factor mortality is among the most accurate measurements of society. Yet there appears to be no mention of it. Did I miss it?
