I'd like to believe. indeed, some results are good. as i said, after
many many trials with the sliders

i only work with matte paper now, whereas museo portfolio seems do be
more difficult to profile than others. however the kind of correction is
always the same: i have to boost  blue (slider value 10-15), and magenta
(5) (and slightly change some other silders)

thanks, this is interesting .
i don't understand neither.... 
i must correct to  profiles with the sliders. see above.

epson archival matte (too epson semigloss) works well with its standard
profiles. if there is a very slight color cast, it's toward magenta
(about the inverse of the unprofiled printer standard). these profiles
belong to the most neutral ones. but with matte paper there is very
little saturation for dark colors.

before i was using spyder . i employed canned permajet and ilford
profiles. they were good (but not perfect), some hahnemühle profiles
worked nearly well.

nozzle are ok.   i tested often... the print quality is very stable.
(unlike that one of the r1800)
beware: the nozzle check is another problem, everybody who's  interested
in nozzles should read the message 95695 in the
DigitalBlackandWhiteThePrint group.

yes with all of the spyderprint profiles. hardly with some others. not
at all with the museo max profile. by the way there is a very easy test.
in photoshop you create a blue gradient, then study various soft proofs...
first, i thought, this is only theory, until i had to print some blue photos.

yes. and i usually try the other intents too.

yes, see above

 i did a lot of this test with the 21step wedges from QTR, uses little
space (25 tests on a A4 paper)

what you write about the r1800 is amazing. i have the same printer too.
as it lays down far too much ink on every kind of paper, i gave up
profiling. how do you deal with this issue? do you ev. use the epson
driver color adjustment sliders? usually i use "no Color adjustment"
