Hmm, I voted for 100%post processed... here's why
This is my workflow:
Fire up Adobe Bridge
Tag pictures which are worth keeping with one star
Filter => 1 star or more
Look at images which require more than simple post-processing, tag two stars
Filter => Unrated items
Look through again, select pictures which may have missed 1st time around (appeal cases =P), tag with one star
Filter => 1 star or more
Open the lot with camera raw, do basic post processing adjustments (exposure, WB etc)
Save the lot
Filter => 2 stars or more
Open individually and give special attention to these images.
Yup... 100% because i do minor tweaks to every single pic that passes round 1.
Cheers =)
