Thank you very much, this is very useful!  Even if it's just one person's
experience, at least it's *a* data point.

May I ask, whay do you think of my RAM-for-ROM tradeoff idea?
Is there one or the other that you more commonly run out of?

Yes, my original algorithm was excessively tricky.  The last (and
fastest) one is actually a lot simpler.
