Calculating the current R number

 

Using my T=6.4 days from last week's post in my equation along with Office for National Statistics data from the last two weeks when the incidence in the population fell from 1 in 55 to 1 in 65, I get R=0.85. The official range this week is between 0.7 and 1. My number is half way so I'm guessing that the range must be the uncertainty added in.
