288 target for RGB, yes. I measured the EyeOne 288 but saved the spectral
data file and then built the profile in ProfileMaker Pro. So the same
software was used to build the two profiles and the same number of patches
but different instruments.

Haven't seen that yet with PM and the 288 target. Even to an Epson 1000. I
got a report from another user that PM failed when the test target was sent
out using No Color Adjustment but worked with a setting of "Photo
Realistic." I was able to get the No Color Adjustment to work fine on my
end.

I've given up on the 2000P but I did get voice mail from the fellow with the
Epson 10000 that said the profiles were great. Again, 288 patches (using the
Spectrolino/scan). I've also had no difficulties with my Fuji Pictrography
3000 and that paper is pretty bright.
