The xff setting is not relevant here: What xff does, is that it specifies what fraction of the required data must be available for a cdp in an RRA to be non-Unknown.
So, if you define an RRA with 1cdp = 10dp, then an XFF of 0.5 will mean that if less than 5 of the dps have valid data, the cdp will be 'unknown'. What you are trying to do is to disable the 'data normalisation' function in RRDTool, which adjusts the stored value based on previous data trends and the received data time. This is useful with continuing traffic data, but not for applications where the value is very small and wants to be stored exactly. Currently, there is no way to disable Data Normalisation (though an 'EXACT' data type that avoids data normalisation would be a nice thing to have) I don't know what your data represent, but it may be that RRDTool is not the correct tool for this job and you should look at a more traditional database such as mysql etc?
