If you look at the page "educate" you'll see he advises 6 min of first development with Dokumol 1+9 or Dokulith 1+3. Anyway, the development times used for the test are the same for all the developers, that's what matters. And in the introduction of the section he mentions the use of Tri-X in all b&w tests.
As for Dokulith, I've been looking for this one too. I had one Orwo UN54 film processed by Frank of this lab, he told me he used Dokulith, and the result is stunning : bright film and nice contrast. When I asked him he advised to look for Dokumol as a replacement.
