Hi Jennifer,
I didn't mean the table wasn't useful. I meant that the "dataset" unit
reported in the table provides little information other than
distinguishing between "at least partially available" (>0) and "not
available" (=0). That information is, of course, quite valuable to
users ... I agree. That's why we created it.
Best regards,
Karl
