It comes round after the desired length.

SMC32 reports the number found, but the number output is limited by those
meeting minimum musical criteria set. One assumes that Mark set this very
high, otherwise he would have run out of disk space!

Yes, Mark is using US billion/trillion, otherwise the 287.9 trillion nodes
would mean incredible performance.

Yes it should, but the US billion is taking over increasingly. It is
annoying, as we are never sure which is being used.
