I always shoot in RAW, as I want to be in complete control of the rendering
my pictures. But I keep quite many pictures that I don't treat, at least
not immediately.
In some cases, say I need a picture of something I'm going to sell on eBay,
or if I want to 'illustrate' something that has nothing to do with
photography as itself, I find it very easy to pick up any picture from my
base; if it still is in RAW format, Digikam allows me to resize (for
publication) and convert it to JPEG in one go and less time than I need it
to explain.  ;-)
And the resulting JPEG is perfectly good enough for this 'instant' need.

I'm not interested in quick/excellent/automated JPEGs. If the pictures are
for my portolio, a show, or even for a customer, I always start working
from a RAW.
RAW+JPEG takes more room on memory cards, more time to be recorded, and I
would have to 'struggle' with twice more pictures to sort/organize on my
computer.

I don't know what a 'correct JPEG' is. On my camera - probably on yours too
- there are several pictures styles I can choose from, each of them can be
customized with 3 o 4 different parameters, that can have at least 5
different values!, the result also depends of your instant choice about
white balance, light enhancement, noise reduction, and whatever else.

When I'm on a shooting, I concentrate - and have enough to do! - on two
things:
 - my subject and how I want to 'capture' it: composition, focal choice,
and such
 - the way I want the camera to record it: mainly aperture/speed/ISO, and I
do it in a manner that lefts me as many options as possible for 'after'.
The rest will have to wait for the post-treatment time: I have no interest
in finding what would be the best parameters for the camera to produce a
beautiful JPEG. It's completely lost time - and action - for me; and when
'the light' is here, believe me, I don't want to loose any time to use it
as best a I can.

I think I should put a warning sign at the back of my van: beware of
frequent stops! because it happens very frequently that I park in a hurry
to shoot something on the spur of the moment, just because light is there.

PS: it was a bit exceptional (but I hope I'll have to do it again in the
future) but on a recent assignment, I took between 800 and 1200 pictures
per day on more than 12 days at a raw. In fact, it was time the tournament
ends, because I had no more room left on my disks and cards, as I was too
busy shooting to have time to sort the pictures. I don't even want to
imagine what nightmare it would have been with twice more pictures...
