Expression analyses allow you to find the largest value of an attribute over a specified time range using the TagMax function. A function which offers the ability the find the Kth largest value (i.e. 2nd, 3rd, etc.) would be useful. Something simi...

Analysis Recalculation produces Out of Order Events, which means they are not compressed. The reason for this behavior is, that there is a more recent snapshot value existing. This also happens, when Recalculation is performed till "Now" (*), beca...
