Maybe if the counted the figures correctly...
There are different measures you can look at, if you have problems with a specific methodology - death within 28 days, death within 60 days, Covid as underlying cause on death certificate, excess deaths against an average.
All these are being produced regularly, and used in tandem. None are perfect, but all will be subject to assurance.
In the absence of perfect data, the correct response is to use it with caution and awareness of its’ limitations, not to throw it out or dismiss it entirely.
