Multiple models predict daily new infections to be anywhere between 20 - 30x under reported (uni of Michigan and I think u of w)
There are enough and more ground reports from various cities of data from crematoriums being >10x more than official counts
There is large scale, govt backed effort to not report in a few states for ex UP which is most populous - govt was directing labs not to take samples. and no admission to hospital as corona patient until you provide RTPcr test id(this is from a friend who's in the state capital and father's in the hospital now). Death rates 10x official counts overall wouldn't be surprising at all.
