Hi  
As it shown in following screen shot, I try to get Delta value(Max -Min) from a tag in every 10 min interval, but the result it always zero for me.  
I really hard time to understand what I did wrong. Obviously I have value in those ranges.

If I use system.tag.queryTagCalculations() I get correct result in that time range.

Is the behavior the same if you use the Query Mode `PointCount`?

Yes, it is the same, but if I change the query mode to calculation it seems it works.  
Interestingly, CountOn/Off, and Average work perfectly.  
It is really easy to recreate with one tag to add history to the Onchange mode.
