IF (and only if) you feed in updates exactly on every step boundary (and remembering that the refernce is always midnight 1st Jan 1970 (unix epoch), then yes, the value stored for that step will be what you feed in - subject to any conversion required (in this case subtracting the previous counter value to get the difference). Under any other circumstance you will get normalisation. This is a commondly asked question, and the simple answer is that RRD Tool is not designed to store original values - it is designed to store rates. Any fudges to make it store accurate values are just that. Also, rates are always stored as a floating point number.
