Recommended practice in a home with more than 16 (or 24) zones?

I've seen both happen in tests, but most often it's the second scenario - which isn't as likely to cause an issue as in most cases, people still turn all the rooms on/off at the same time anyway.

Got it.  Thanks.   Any known issues with my other approach: all inputs into Matrix #1 (32 inputs is enough for my project) and use spare digital outs on Matrix 1 to feed Matrix 2?  I could make this my universal solution by putting ADC converters in between Core 5 analog outs and Matrix #1 (I haven't noticed any quality loss).  The ADCs would be required since PulseEight doesn't route analog inputs to digital outputs, but it will route digital inputs to analog outputs (if PCM stereo). Then there would be only one valid path from Core 5 to Matrix #2 zones (via Matrix #1 and NOT direct).   Or would Core 5, nonetheless burn a new output to feed two endpoints on Matrix #2?

Obviously it is better to just get a properly sized matrix.  Since I don't have that (and I have 54 zones!), I guess I'll have to live with any glitches (which I haven't noticed, but I also haven't done rigorous stress testing).  But your explanation above gives me some good ideas for testing.

Bigger matrix is better, but while a matrix to matrix is not ideal as it could limit total available connections, in this case it's better than splitting controller audio.
