Your hack was pretty cool, but it's not really handy to implement as a
generic solution for GCM, we need no fuss solutions.

This works very well for me... and would be a great default for medium quality:
  argyll-targen -v -d2 -f 210 xxx
  printtarg -v -i CM -h -T 300 -p A4 xxx
  colprof -q m -a l xxx

For low quality the -h parameter can be dropped from printtarg, and
lower the number of patches to ~90, whatever fits on a A4 piece of
paper...

One the the main problems is that these settings can vary from
spectrophotometer to spectrophotometer...
