It is I expect simply because Gov UK - the official site for data - is regularly behind. It updates at 4 pm on days it is working (it has been very late twice this week due to different issues) but the England hospital data is often not added until late at night and at weekends might not be at all.
For the other nations it is always at least a day behind and up to 3 days behind at weekend.
As of this morning it is up to date for England but has Thursday data for the other three nations and will likely stay like that until Monday evening now.
The data is easy to access as the other three nations all announce it before 4 pm every day and I post it in here- but Gov UK still always 'updates' at 4 pm to the day before for the three nations not to that day.
Its a small thing. Am I being pedantic? Very possibly. And I do not think there is an agenda behind it. I just think it is laziness.
However, that is why I am concerned. Because it begs the question what else are we happy to have less than up to date information on at a top level in the midst of a pandemic? Especially if on that day you are making a point about being over 12,000 in hospital which must have been pre planned as it was repeated several times. It had not been over 12, 000 then for more than 24 hours in the published data. And it just infers sloppiness that nobody bothered to take a minute to look up the true numbers before making a big deal of this nationally.
As I say I am probably just being overly fussy as I freely admit to being a tad obsessed with the daily numbers after posting them for months now.
