From React-1:
R down to 0.88

"The results of these tests suggested a 30% fall in infections between the last study and the period of 13-24 November.
Before that, cases were accelerating - doubling every nine days when the study last reported at the end of October.
Now cases are coming down, but more slowly than they shot up - halving roughly every 37 days." - BBC News.

Every 37 days - I doubt the tiers will keep the R below 1 for long.
