It's weird. Even Chris Whitty has been saying this, JVT spelled it out carefully and clearly a few times.
The criteria has been changed at least once. We KNOW that deaths are over reported because of the difficulties in determined cause of death in community cases.
We KNOW, again because of various podium talks, that excess mortality data will, eventually, be the most infomrative data we will have, that every country will have.
And yet still the accusations of lying, obfuscating, fearmongering continue.
We either have not enough detailed data - which many can't analyse anyway - or we have to much data and are being drwoned init, manipulated by it.
And still the usual, always been there, data is available for anyone who cares to look at the ONS and other public data streams.
That the ONS have this data and have publised at, as they do whole tranches of other data, is how they work. It is updated every time they get enough data to correct for confounding variables.
They are doing this in real time. They can either gie us the daily reported data and correct it later - leading to accusations of incompetanc and fearmongering - or they can wait for the adjustments to be made, leading to accusations of hiding things, lying etc.
Again, we have had these adjustments explained again and again.
It REALLY isn't news!
The data adjutsment is... but not the fact that it happens.
