Interesting. Was just thinking about this.

The best advice I can see (someone really needs to do a write up about it) is just track the orderbook and see what offers are already in there. It's pretty easy to see that smaller amounts and shorter durations are less valuable to a cj (sb please tell me if I'm wrong on that.) I just moved a few smaller utxos into cj wallet to see what to expect first. At least while I'm figuring out all of the above and the questions you asked.

From my experience, running joinmarket client server is great to get to understand the technical side of it, but we really need the UI to make it clean and frictionless for those of us just learning to use tools like languages like python.
