They don’t mention Diamond Princess IFR estimates in their paper, though. In fact, the study doesn’t cite other studies on IFR estimates for SARS-CoV-2 at all. I don’t get what’s going when soemeone writes a paper with a conclusion that’s 5-10x lower than all the other estimates before, but instead of including a discussion on why this might be the case or how it might fit with apparently contradictory data points (e.g., the cruise ship IFR or South Korea’s IFR), they just move on to the next paper. Credentials or not, I find that process pretty dubious. I realize that there’s an implicit hypothesis in the paper that “because transmission is stronger than we thought, others might have underestimated the number of mild or asymptomatic cases.” Okay, but that hypothesis is contradicted by data points he must be aware of (as you say, he wrote papers on the cruise ship). Why is there no discussion on this?
Not sure: the Diamond Princess is mentioned in this preprint and in fact one of the authors of this preprint wrote two papers on the Diamond Princess:

So I think they thought about this,
