One thing (important) more. You must have set perceptual/actual

correctly. It is also important to have it perceptual (as discussed
earlier) to get safer separations by pressing CMYK-tab.
Doing so, I think you waist a lot of quality of your rgb-files and than the
question comes up why we are always talking about staying in a bigger
rgb-space instead of a small cmyk-space.
As I said earlier, the perceptual intent is only to recomment, when your
picture is as saturated that it really fills out the hole (choosed)
rgb-space. If you would use the perceptual intent with a picture that does
not content more colors than already would fit in your cmyk-space, you would
loose more colors than necessary. Therefore of course you should use a
relative intent.
As a backround for my provocative writing:
I am working on a prepress-department of a magazine publisher and
therefore we must "sometimes" use a smaller cmyk-space (still
converting manually in scanner or preferably in PS6, not archiving
cmyk). We are scanning and/or fixing about 40 000 pictures a year and
we have many/manykinds of presses. So I think it is best bet to have
default rendering perceptual if somebody just takes preset
colorsetting and hits CMYK-tab. Not always optimal, but much safer
than relative. The preferable way to convert is naturally manually
(convert to profile...).
Personally I use mostly perceptual rendering, because it brings more
pleasing skintones and more shadow-detail. When I find some picture
benefits from relative intent, I use it. If the picture is not
optimised (originals are not always optimal...) or if it is somehow
out of order, it is best to fix it (also saturation) first, and then
see which intent fits best.
And then there is coming the day when your pictures are converted in
a color-server (or in-RIP in press), all with the same intent. And in
this kind of working enviroment it will be perceptual.
Personal/artistic production is other thing and mass-production
other, money/time is making many decisions for you. Many times you
only have choice to be sure that you can get predictable decent
output, not always optimal.
Sure there is many "workflows" that can use mostly relative
rendering, so the default for them is relative.
