How are they testing in Spain though, and how much? I'd be very careful with getting any conclusions at all from the case numbers - I think, if anything the death numbers in the second table are more 'solid' in that sense. Also, they don't mention basing their calculation on some kind of running average (unless I missed it?), so while the decrease in speed is of course great to see, the numbers would be a lot more dependable if they weren't exposed to the types of random ups and downs (noise) in the daily data.
There's a lag of up to a month in the death rates, though - there's a leading/lagging indicator problem with all the data here, and none of them tells us the real infection rate.
