I'm guessing that you're doing 2-pass encodes and the "Final Ratefactor" is what x264 uses as a starting value for the second pass. It will constantly adjust it to reach the desired target bitrate.

If you're using de-noising filters, the compressibility increases and therefore the quality (i.e. the rate factor) at a given bitrate.
