I know there's an earlier thread but wanted to start fresh. First a few of the 'findings':

PDFs with more than 100 bookmarks will not convert to Print Replica
Update: This seems to be fixed now. Kindle Create still has issue with it.

ePubs with more than about 1300 ToC entries fail to convert
Fun fact: most editions of the Bible have 66 books and 1,189 chapters, so a ToC with entries for all of these would probably get through S2K's pearly gates. Maybe that was even the standard used for the arbitrary limit?

In this case Kindle Previewer 3 does not complain, but it gets rejected by S2K. The only recourse seems to be to thin out the ToC entries somehow.
It's also possible that it is triggering some sort of timeout and is not a ToC size limit as such. It takes about 40 minutes of processing before failure occurs. Calibre can take hours to convert these (hmm why?).

Conversion to Print Replica will preserve Bookmark hierarchy in its ToC
Bookmarks are converted to Print Replica ToC entries, and at least one level of hierarchy is preserved (have not tested more than that). Generated PDFs often lack any bookmarks and thus will have a minimal ToC by default. So it is nice to add some before sending it for conversion. I've seen at least on GitHub project that purports to automate this (scans PDF for things that look like headings), and am hoping eventually to script it myself (I plan to add page links for page references in Contents/Index/Footnotes too).
Kindle Create does not seem to let you create a multi level ToC, and if you make changes to one that's been imported, it gets flattened.

FWIW I sent Amazon Feedback about the Print Replica ToC limit (seems way too small). Probably should send one about multi-level issue too.
