I see.

Is there a way to retrieve the exact value ?
I am using RRD as an easy way to collect all my data and perform
simple statistical analysis on it (average, max, min).

But I want to be able to retrieve the value of an interval as it was
entered for that interval.

Yes that is true.
It will take between 35s to 40s for my script to collect the data
before it can be fed to RRDtool.
