Agreed. Also, our understanding at the time was that people were spreading it in the days before developing symptoms. Does the Stanford study adequately sample that population? We have no idea, because this study wasn't designed to answer questions about asymptomatic spread. All they did was run a special PCR test on a convenience sample of people they had lying around in the hospital, and report the results they got from that. Maybe most of those people were post-symptomatic, which would explain why they had a lot of dead virus lying around to be collected in the swabs. If these findings had revolutionary implications, they could have been surfaced at the time. Other people at Stanford had no issue broadcasting their opinions and getting heard.
