I may have misunderstood what you meant by: "t's those JPEGs that you're editing with the slider bars in the dashboard" But iPhoto generates a new jpeg file based on your adjustments from the original RAW file. It does not just apply the adjustments to the jpeg file it has already generated. I confirmed this by changing the RAW file in the file system and making adjustments. When I hit done the adjustments where made to the new RAW file.

  Well, I'll tell you what I've experienced step by step, and let you decide from there. First of all, I'm talking about working strictly within iPhoto 5 and not making any edits to any files using an outside image editor.
  
  The original RAW file is located in the "Originals" folder. iPhoto 5 reads the data from this file to generate a jpeg that is stored in the "day of the month" folder.
  
  When I edit a picture in the iPhoto GUI, it doesn't make any changes to the original RAW file. It does, however, generate a new jpeg in my "day of the month" folder.
  
  Apple claims that iPhoto 5 reads data from the original RAW file when you edit with iPhoto tools, then generates a jpeg based on the changes you've specified.
  
  So, you're not changing the RAW data itself; you're actually generating a new set of instructions for interpreting the data, that results in a new Jpeg that's displayed in the iPhoto 5 interface.
  
  This is a somewhat confusing process, but it makes perfect sense to my mind. I should have written that sentence better. But in that section of the article, I wanted to focus on the convenience of being able to work with Jpegs and not having to go outside of iPhoto just to generate a slideshow based on RAW images.
