Time to ID (hours, 1 week moving window)
TTID
is time to receive an identification from someone else, and
TTCID
is time to receive an identification from someone else that matches the community taxon.
These stats are made for observations created for a week prior, which means it will miss identifications added to observations after more than a week, and thus make the stats look lower than they would if you computed them again in the present, but they should still provide a decent measure for how fast the community is at identifying within 1 week windows.
Note that these stats are only for observations with photos.
