All I was saying there was that if you do adjustments to exposure and contrast etc whilst in RAW you are not affecting the IQ (within reason). You can usually get away with more significant adjustments in RAW than after you convert.
And remember - although you might have a work flow that minimises the need to resave JPGs, the fuile has already been converted and saved once in camera, you are then saving a second time. If you start work on a RAW and then save you have only compressed once.
