Quite right Steve.
If it is broken to start with editing the profile isn't going to fix the
profile to make it more linear. Yet if the profile hasn't been able to bias
while creating the profile certain colours or grey balance due to the
non-linearity you can choose to edit these flavours while obviously dropping
others that the profile creating application tried so hard to do.

editing is something to look at last, try to fix it before.
I'll add one more thing. Past experience with Heidelberg PrintOpen version 3
and 4 let you manually edit measured patches with guesses to the counter
action you want to do before creating the profile. This at first seems
ludicrous , yet is it? By pre-editing the measurement data you are still
leaving the profiler to create it's best tables even though you've hacked
the measurements. Give me a smooth profile over an iffy edited profile any
day.
Profile editors all have to rely on a certain resolution in the profile and
if you start to move things about you will quickly come up against points
that are broken away from the original tables that may show up now in test
prints or many months later.
So for a photographer to edit a quick profile for user preference is one
thing that Gretag had in mind with the i1 Match editor, yet a professional
printer will be well advised to resort to profile editing with much
precaution and sound reasoning before going that route.
