Any company dealing with the fda and testing will never put out a time line. That would open up lawsuits like no other. Just idiotic to think there would be a official timeline released to the public/shareholders. The doctor and JHU probably have written ones for themselves to try and follow but other than that.
Like you said a forecast yes, hell construction companies put out a estimated finish date. I’m a electrician and I have not been on one job that has had a exact finish date until we actually got about a month out.
