That's the intuition, but I wonder if there isn't a spike in near-term repurchase behavior that the algorithms are correctly exploiting?
Ex: I bought a vacuum, but I'm unhappy with it. I bought a pool or oil filter, but it was the wrong one. I bought an X, but it was defective. I bought an 8-ct of paper towels because I run a cleaning service or property management company and use a lot of paper towels. I bought a pair of jeans and they're the wrong size or I bought a pair of jeans and they're exactly the right size and now I want to order 3 more pair so I can have the ones I like.
Years ago, we built a conditional offer engine and the humans operating it kept complaining that it was "broken" because it was suggesting non-sensical combinations. In split-run, those non-sensical combinations were clear winners, even if the humans couldn't get comfortable with them.
