Testing's only 2/3 what it was on 30th October. It's not as simple as we've only picked up 2/3 of the cases we should have because people who are more certain will surely be more likely to get a test, but is that because people are avoiding being tested
I think there's a good chance it's simply less excess testing, due to half term, and the university "test everyone" has faded away, and with "work from home", jobs will stop asking for as many tests - so it's more limited to just the people with real symptoms - as it really should have been all along.
There's been no change to anything that would stop people wanting to test, the restrictions haven't change, I can see that happening during lockdown itself - as people won't see the point if they're locked in anyway, but with the Tim Sepctor data point too, I don't see any alarm bells with inconsistent things.
