At some point I went through the code to try and understand the
"random" cuts thing (I think it was part of the log generation that I
was interested in). I've probably forgotten the important bits but Riv
tends to favour the least played cuts. There is still a random element
on top of the least played bit but obviously newer = higher chance.
When you've had a system running for a while so station IDs are in the
hundreds or thousands of plays, adding a new cut almost guarantees,
within normal probabilities of randomness, that you won't hear the old
stuff for a while.

In the days of magnetic tape cartridges, a "cart" was a physical
plastic object containing a loop of tape. You could wind any amount
of
tape onto a cart, up to about 10 minutes in an NAB Type A cart, which
was the only type most radio broadcasters used (there were larger
type
B and Type C carts, the latter used in backgrouond music systems,
where they held up to an hour of audio).
The tape was an infinite loop; just before the beginning of each cut
was a Stop cue, so you left the cart running after the spot or song
was done, and it would cue itself up and be ready for the next play.
You could put more than one cut on a cart; for instance, a
three-minute cart might have three :60's or six :30's. If you have
multiple versions of a spot, you could use this feature to make them
rotate evenly throughout the spot's schedule.
This brings me to a minor quibble with Rivendell: it doesn't work
that way. Instead of rotating the cuts in a cart successively, it
chooses them at random, so you can't make them rotate evenly. You may
get the same piece of copy twice in a row, which is probably not what
the sponsor wants.
I have a client who just added several new top-of-hour station ID's
to a cart, and he's reporting that only the newly added ones are
playing; the older cuts don't seem to play at all. And yes, he's
running 2.11.0.
