The register ranks every live listing by what a unit of earning costs — the price a buyer pays divided by what the Machine earns, with the cost of switching a dormant one on added in, because that travels with the sale. This asks it backwards: for the Machines you own, what would you have to ask to land at each rung of that ladder?
Best value is what you would have to ask to be the cheapest earning in the collection — the top of the register. Top ten and median are the same sum against a lower rung, and best on desk is the cheapest on that Machine’s own desk. Type any price into the last column to see where it would actually land you.
List here opens that Machine at this site’s own counter, with the price sheet already on it — one approval and one listing, both signed by your wallet, against the market contract the register reads. OpenSea opens the same Machine on theirs, where their sell flow lives; they have no link that opens it straight onto the listing form, so that one lands on the item page. Nothing on this page signs anything or asks your wallet for anything but its address.
