Think of it this way, if you have a measurement of 10 units in a 5 minute period you think you would have the value 10 stored but the per second rate would actually be 10/3600 = 2.7e-03. That's the value that gets stored since everything gets stored as a per second rate.
MAX and LAST won't change the stored value, just the way it's aggregated.

Also, shouldn't that change if I use MAX or LAST as the DS type?
