The 70s ticketing system ran off of "buckets" where availability of fares at various prices wouldn't appear until previous buckets were emptied, or time ran out. I don't remember the details (my only sleeper car trip was paid with Amtrak miles) but if you studied it and worked it you could predict when new buckets would become available, or when a bucket was about to "expire" and the price might drop. If I remember right there was a sweet spot about six months before, and another very shortly before (and if you wanted to be risky, and knew the line, you could get a coach ticket and ask the conductor to pay to upgrade on the train - that is the cheapest of all if there is space available as it basically ends up being the cost of the meals).
It's also a bit weird in that if you know some of the limitations, you can do things like get a sleeper for overnight only (from the stop around 5PM to the stop around 8 AM say) and then get a coach ticket from then on - which if scheduled right would end up being the sleeper for the whole trip as there's no point in resetting the room.
You could also book "insane trips" that the system wouldn't let you do but were perfectly doable, because it wouldn't correctly recognize that you could make the layover, etc. People would also try to trick it into letting you book trips that wouldn't make sense unless you're trying to ride the train for as long as you can (sleeper car mile purchases were "zoned" in the past - so anything in "Zone 1" would be a fixed amount of miles). They've since changed that to the more standard "miles are just pennies against a normal fair" type of reward.
This is much less doable now than it was some years ago. Amtrak's revenue management has gotten a lot better, and most long distance routes start at the highest bucket pricing, and only drop down into lower buckets if demand sags. Demand is also higher than it was pre-COVID, and I don't think you can predict when buckets will expire.

This is also risky, as it depends on the largess of the conductor, who is totally within their rights to kick you out of the sleeper and down into coach at the appropriate time. You also would not get the included meals during your coach segment, and would have to pay for them in the cafe car.

Amtrak has also introduced a pre-train bidding system for empty sleeper car upgrades, so its very rare for a popular train to have empty sleeper car berths that can be purchased from the conductor.

Making any Amtrak trip dependent on tight layovers is a mistake, in my opinion; multi-hour train delays are somewhat common, and unless you are booked on a single ticket, Amtrak will not hold a train for you, nor will they reschedule you on a future train if you miss your "connection" between two separately ticketed trains due to their delay. My advice has always been to put an hotel overnight between any connection involving two unrelated trains; it makes your whole trip a lot less stressful.
Yeah, the usual "layover it won't let you book as a single segment" that I would look at were the ones where the system deemed it too long and wanted to count it as two separate trips.
