Here's what Indiana hospitalization outcomes look like, both since March 1 and since August 1. I tend to discount the early data relative to percents of COVID+ cases since testing was so scarce early on. I know people in early July who got tests approved because they had flown to other states, so July is probably valid also, but prior to that, I think there is just too much unknown from lack of testing capacity/availability.

Not sure how the hospital mortality relates to the metrics you quoted.
There seems to be something wrong with their numbers.
I do not believe that the recovery numbers are identical for those different time periods.
