Yea, I agree that the case counts are very different between regions. I think the more interesting column is the IFR estimate based on the antibody study results, since dead is dead as you say. It is interesting though that the median undercount is converging to ~10-20x. Perhaps the protocols across regions are similar enough that the confirmed case counts are somewhat comparable.
