I had an e-mail exchange with him a year or so ago so he does (I hope) still read mail.

I think the main advantage of Bert's system was it de-coupled--- some people seem to have de-coupled their brains in this thread but that's another set of topics--- user judgement (and user error) from the printing process--- no need even for a "perfect" print for calibration or even to know what a "perfect" print looks like (and in the end all prints are "perfect").
His final version.. btw. I think requires a Colorstar or Colorline analyser alongside a good Status-A reflective densitometer.. and (worse of all) Microsoft Windows 2000 or newer..
