EERC is counterpoint_id 606. Could select by bounding box (lat/long) too. This includes a list of counts (just labeled “id”) but no actual counts, so you could do time/date collection stat comparisons from there as well.
It looks like minutes start/end on the second that the count was started, so aggregation by minute (not second) should be used.
It looks like minutes without data are excluded, e.g. no 12:51:52 minute is included here (EERC 606):
