Normal values calculator link
I'm thinking that the normal values calculator link needs to be removed. It points to a page with somewhat deceptive big buttons that lead to third-party sites for file conversion/driver update software. TPSwiler (talk) 16:41, 4 May 2020 (UTC)

I just updated the link to point to the CDC calculator instead. TPSwiler (talk) 17:10, 4 May 2020 (UTC)
