Because your whole approach was, and still is dismissive of everything I've been saying about the fact of London's lower "r".
because it's unlikely.
I have pointed out for weeks that UK government claim of R (should really be called Re) is too low to be credible. It should be around 0.9.
Most people cannot calculate R nor collect data to spot issues with government claims.
Re changes with mitigation measures, therein lies the rub.
If Re is 0.9, it's unwise to lift lockdown.
Today, government CSO Vallance said it's between 0.7-0.9. Nearer to the truth but not quite.
If government were to be believable, they should have used antibodies test statistics instead of a complex notional factor like rate of infection.
from wikipedia:
Effective reproduction number
In reality, varying proportions of the population are immune to any given disease at any given time. To account for this, the
effective reproduction number
is used, also written as
, or the average number of new infections caused by a single infected individual at time
t in the partially susceptible population. It can be found by multiplying
by the fraction
S of the population that is susceptible. When the fraction of the population that is immune increases so much that
drops below 1, "
herd immunity" has been achieved and the number of cases occurring in the population will gradually decrease to zero
