And you said the ISU number was 906. Where did you get that number for ISU students because Wintersteen showed 633 for the 14 days?
My point was that the NY Times article is not for just ISU, or testing done at ISU. It's for the entirety of Story County. 906 (from the NYT article) lines up with the Johns Hopkins numbers that I linked. Wintersteen's 633 are either just students tested at ISU, or ISU students (not including everyone they have infected in the community) - but that does not matter to the NYT numbers. They are for Ames/Story County as a whole. I don't know why she would argue with the numbers for the entire city (which is what is stipulated) saying they don't match ISU's numbers - they aren't just for ISU.
You can, however, look at the fact that ISU students (as defined by Wintersteen) comprise 70% of that total in a bubble. That's fairly shameful.
