Ah good, finally back to statistics
Barracker's volcano informative as ever 
"nearly 10% of the reported deaths today being over 4 weeks late.
..... and many more were 1 / 2 / 3 weeks late
This must be of concern to the govt in their planning to exit lockdown:
With so little testing,
the government is quite reliant on these death totals to warn if exponential infection growth is starting
However, the death stats at any time would be very incomplete
and of course the care home deaths are also delayed
Hancock must organise a proper mass testing system asap, expense no object
The proposed App could help to some extent, but requires a lot of public cooperation
and also IT projects under all govts have not gone well
Many thanks for the new contour plot, shoots 
They are excellent and give a very clear picture of the distribution in the country
