It is almost impossible to get very accurate causes of deaths for all patients during an epidemic. Doctors are required to specify a cause of death on the death certificate regardless of whether adequate testing has been done. but it's rarely just a guess. There are difference in how the disease process progresses with Covid 19 than other repertory disease. In cases where there is no clear evidence that cause of death was covid 19, how a person contracted the disease is a major clue in an epidemic. In other words, if it quacks like a duck, walks like a duck, has feathers and webbed feet like a duck, it's probably a duck.
I have to disagree with you on this. Here is why again, and since I already wrote about it before, I'll copy from previous post.
To test for corona virus, they're using something called RT-PCR, you can read about it
here. What's wrong with the test is that is not looking for corona virus directly, but for presence of certain strain of RNA, and since it's believed that corona virus is an RNA virus, there is certain RNA wrapped in proteins. Where it goes from there... they are assuming that if that RNA can be detected, than patient must have corona virus. It's assumption, not certainty, and that's fallacy, because there is nothing to prove that RNA that show positive test did not come from some other source, like bacteria, fungi, or patient's other cells.
That's why there is big question about legitimacy of confirmed cases of corona virus. While it's true that RNA could've come from corona virus, it could have come from tons of other sources unrelated to corona virus. Now, how to actually prove someone has corona virus for real, what would be proper procedure? Well, that something called purification... way I understood it is, they need to find exact RNA protein structure of corona virus, purify it, then extract RNA from the structure that match original RNA found in Wuhan, and only if those are the match, than person has corona virus.
No diagnostic test is 100% accurate, but experts have still expressed concern at the accuracy of the COVID-19 tests.

Since they're not doing that, there is no actual proof of the corona virus itself, just proof of presence of RNA that could come from various/different sources. Regardless of suspect nature of their declared number of "confirmed" cases, the possibility of confirming the corona virus is not achievable with current testing kits.
For that reason, total death count from corona virus is not just inaccurate, it's way overblown.
