You're not being realistic in your numbers because you are assuming a large number of infected but a symptomatic that will not go on to develop symptoms and die at the observed rate. Where we have accurate data, that data indicates you are wrong to assume that asymptomatic when tested means that they will remain asymptomatic. But the worst assumption you are making is that physicians don't usually know what people die from, or worse yet, you may be assuming some left wing conspiracy to lump all deaths in with CoVid deaths. If so, this is lunatic thinking.
