OK, it looks like I've overlooked something. You have two 
consolidations, both with the same resolution (one hour, or 12x5 
minute steps), but different lengths ?
If so, why ?
There is NOTHING you can do with the shorter one that you cannot do 
with just the longer one - so all it's doing is costing you storage 
space and processing time.
I'm not even sure how you would select which of them to use - other 
than trying to graph/extract data longer than 14 days will 
automatically use the longer one.
