Daniel,
It may well be that the profile does not reflect a current process
standard offset printing. The profiles themselves date from 2000, the
data from which they are built is almost certainly a fair bit older.
Gray balancing on press rather than in the separations is the
exception rather than the rule in the US. It's an idea whose time has
come, certainly, but it's still counter to the conventional wisdom. A
profile simply describes the condition represented by the measurement
data.
I firmly believe that standards-based printing is the inevitable
future of print as a manufacturing industry, but all "current process
standards for offset printing" are still ongoing research projects
rather than stable established standards. In 1999-2000, that was even
more the case.

1.) Dan Margulis' comments refer to the old, deprecated Custom CMYK
feature, not to any of the v2 profiles.
2.) The Euroscale v2 profiles were built from published FOGRA data. If
your press conditions conform to that data, the profiles work
extremely well. If they don't, the profiles will not work well. It is
nonsensical to complain about "profile errors" when your press
conditions don't match the conditions the profiles were built to
describe...
Thanks, Bruce, for your comments.
Yes, the profiles from ECI-FOGRA works very well. But the Adobe
profile "Euroscale coated V2" based on the FOGRA data don't work as
well as the "ISOcoatedsb" from ECI which is theorically for the same
paper and press conditions. The "ISO coated" is the "official" profile
from ECI-FOGRA for the coated and glossy paper conditions.
With the ISOcoatedsb (and all other profiles from FOGRA) we obtain a
very exact gray balance. It is'nt the case with the Photoshop 's
Euroscale profile. We obtain cyan color cast on print (and of course
red color cast on proof preview). I dont know what is the error in the
Adobe Euroscale coated V2. It does not reflect a current process
standard offset printing.
