The rules in Ross' books are guidelines, and they certainly don't
cover all the cases.

LilyPond does not use a hardcoded set of rules; rather, it tries to
score different configurations, and pick the one with the best scores.
 This is a technique that works much better than hardcoding different
rules, but in some cases there are small divergences with the
'prescribed' quants. We even have a regtest for it, see

It might be possible to tune the scoring parameters to copy Ross
exactly, but probably some other configurations will fall over.
