I have two files currently on my hard drive, both extracted from a K-3 DNG, neither of which reflects the JPEG settings (highest quality) on the camera.

I used dcraw with the -e option to extract the preview file, not Faststone. The byte count of the extracted file reflects the count as recorded in the EXIF for the JPEG preview image, not that for an in-camera conversion.
Is there any chance you are actually saving a JPEG conversion of the RAW image?
As for people arguing just because they can...I don't know that you are being mocked. You suggested that RAW+ had little utility because it is possible to use a computer running Faststone to extract a full-resolution preview JPEG. In the course of defending that assertion, it came out that there is indeed a full resolution JPEG preview image included in the RAW. Ding! Ding! You win!
Very cool, in my opinion. There is also no doubt that you can CTRL-S from Faststone and get a JPEG. Whether that file is the preview image makes little difference. I can also do the same quite handily using dcraw*, but FWIW, I find that much less useful than simply using RAW+ or doing the in-camera conversion on a per-file basis.
* Faststone uses dcraw internally
