mp4.video.preset quality preset %

Are there  any  numbers  on how  much  loss  is associated with each 
preset ?


mp4.video.preset:

Preset (encoder optimization settings) to be used while performing mp4 
conversion.Valid values are: *ultrafast, superfast, veryfast, faster, 
fast, medium, slow, slower, veryslow*

*
*

Could  we  add something  like this :


**ultrafast (40% quality loss) , superfast******(30% quality loss**)**
