Na, I think that the flu-stat arguments were before your insertion as the pain-in-the-ass
de jour 
Someone here who works in the medical community did make a good argument for how the big numbers were generated from small samples. As as engineer, I have a built-in suspicion of this practice, because it seems that all the interesting bits of data like to hide in-between the sampling events.
Excess-death comparisons are usually subject to the accuracy of the model being used for the comparison. One can do sort of simple extrapolation like "the population grows by about 2% each year, so excess deaths should grow by the same amount and so there's my baseline". Good, but not great. Then there are the "American models" and "European models" and so on that take into account more detailed demographic factors and establish upper and lower confidence limits, and just like any other sophisticated model, we can make those tell us anything we want.
But if you look at overall deaths in the past few years:

... it shouldn't take a model of any sort to show that something really, really bad kicked in during the spring of 2020. The interesting thing of course is that the number of excess deaths in 2020 exceeded the number of "died from/died with" Covid deaths by about 150k, or roughly 40% more. This would appear to be the basis of the argument that lockdowns killed a lot of people, and I believe it (particularly if one starts breaking down excess deaths by age group, and finds that the 26-44 group suffered something like a 25% increase despite not being particularly vulnerable to Covid).
Where I have problems is with the people who want to buy into the CDC numbers when it supports their argument but then discredit those same numbers when it supports something they don't want to hear. I don't know how it become so impossible to support the theories that: 1) Covid killed a ton of people; and 2) things we did in response to Covid (such as lockdowns, a suspension of medical services, and possible the vaccine) killed a ton of people. But the Venn diagram of people that support both of those concepts in their head simultaneously appears to have a single-digit population.
If the vaxx has killed ~25,000 people in the past five or so months, those numbers will likely show up here as well - particularly since they'll occur in the summer months where we would expect fewer deaths. Meanwhile, props to whomever decided to mine the data using those codes; that's pretty creative, and not the sort of concept that would have been developed by the "all the data is fraudulent!!!1!1!!" crowd.
