And it definitely suggests that the amount of under-reporting varies by area, so it's even more unfair for you to multiply the entire country's number by 100 as your goalpost.
There are however, other reports you can quote:
- The Print (not govt-leaning) "If you claim India’s Covid death toll is 2x govt figure, it’s understandable. But not 10x" [1]
- NYTimes: Bhramar Mukherjee, an epidemiologist at the University of Michigan who has been following India closely. “From all the modeling we’ve done, we believe the true number of deaths is two to five times what is being reported.” [2]
In short, I strongly feel throwing numbers around without basis simply widens the chasm.

Extraordinary claims (such as up to 3 million deaths in ten days) require extraordinary evidence. My response, if you notice, was specifically about that claim. And I also did not fail to mention that deaths are underreported.
