Hi all! Using the example below I have completed a test using a larger book. This time I downloaded War and Peace from the Gutenberg Project and extracted the individual xhtml files for Context. I played around with the setups for the align:pass:test4 code below, as Hans suggested, and it was changing the \tolerance value which made the difference. Increasing the \tolerance value to 1000 eliminated all overfull hboxes but still left 79 underfull hboxes. I continued to increase the \tolerance value up to 6600 and was left with two overfull hboxes. One with a badness of 6641 (warAndPeace1.png) and one with a badness of 1097 (warAndPeace2.png). Above the \tolerance of 6600 only warAndPeace2.png was left with a badness of 1097. Both of these underfull hboxes were at the beginning of a paragraph - "To his Honor" in the first png and "Well, you see," in the second png. I not sure a reader would spot the second png badness but the first is noticeable to my eyes. I'm very pleased how the book has turned out, all 1668 pages of it as an approximately 13cm by 20cm book. The pdf is 4MB and each run in ConTeXt takes about 10 seconds on my M1 mac mini. I'm interested in seeing how \setupalignpass develops and learning more of how to use it.

Hi Keith,
Here an example that Mikael made for such a book:
\showframe
% let's very strict
\startsetups [*default]
\directsetup{*reset}
\frozen\widowpenalty 10000 \frozen\clubpenalty 10000 \frozen\displaywidowpenalty 10000 \frozen\brokenpenalty 0 % \defaultbrokenpenalty
\stopsetups
% we enable the use of expansion (this feature might become preset % because we now delay setting the vectors anyway so less overhead)
\definefontfeature [default] [default] [expansion=quality, protrusion=quality, itlc=yes]
% vertical expansion
\setuplayout [vz=2]
% for which we need:
% \setupalign[hanging,depth,stretch,granular]
\setupalign[depth,stretch,granular]
% here are the passes:
\startsetups align:pass:test4 \pretolerance 100 \tolerance 200 \parpasses 4 classes \indecentparpassclasses threshold 0.025pt adjustspacing 3 adjustspacingstep 1 adjustspacingshrink 5 adjustspacingstretch 10 next classes \indecentparpassclasses threshold 0.025pt adjustspacing 3 adjustspacingstep 1 adjustspacingshrink 10 adjustspacingstretch 20 next classes \indecentparpassclasses threshold 0.025pt adjustspacing 3 adjustspacingstep 1 adjustspacingshrink 25 adjustspacingstretch 50 next classes \indecentparpassclasses threshold 0.025pt adjustspacing 3 adjustspacingstep 1 adjustspacingshrink 50 adjustspacingstretch 100 \relax \stopsetups
\setupalignpass[test4]
\starttext ... \stoptext
(work in progress so keep an eye on updates)
