Are you doing updates every 30 seconds?  Well, if you only have 300
second buckets, then there's no chance you'll get back the exact
numbers you put in.  

For that to happen you'd have to update exactly on the step
boundaries.  

A step boundary is when the timestamp is evenly divisible by the step
size.
