In reply to Philip:
There is so much variability in these numbers that really the best thing to do is to try to look at general trends, rather than focus on a few days results. Firstly, the number of deaths depend on the number of infections of 2-3 weeks before; however we have little or no way of knowing what that number is, or how that corresponds with critical cases of a week later.
A number of posters have noted that reporting changes in local authorities have made big spikes one way or another. There is no adequate testing data that we are aware of, only reports of tests on patients admitted into hospital.
Personally I'm looking at daily changes in infections and deaths reported as these depend on actual test results and the real world.
Finally there are a number of expert statisticians posting on our forum, who are debating the interpretation of the inconclusive data we have so far on a continuous basis, as are the authorities.
You may want to check out Mark Handley's graphs, which are as good as I have found; however they are not particularly optimistic.

Sorry for the negative post; hopefully we'll have a better idea in a week or two.
