The root product (shown in bold) is the square root of the product of the cases and deaths gradient; the interpretation (whether for cases gradient, deaths gradient or combined root product) is that >1 means the growth of the entity is in the 'exponential' zone if it continues.
Countries previous nine root products are shown alongside. <<
Many countries' RP's remain on the wrong side of 1.
The USA root product (RP) drops below 1 as some states reverse lockdown easing, but cases remain >1.
A slight change at 'the top' as cases in India overtake those in Russia, though the latter's RP is back in the exponential zone - especially worrying for a country with a big population; Indonesia too, though its actual death tally being low gives it more time.
Spain's data reporting has been erratic.
On 2/7, the UK announced a revision deleting cases where people were tested twice, hence causing its cases gradient to go impossibly negative. (Hopefully Hancock won't make any claims for this :-) )
When are all these RP's in countries with high deaths going to go down where they need to be - at 0.5 maybe - for the virus to be in check?
