In my experience, no, the AMS has a long, sloooow humidity time constant but filament print quality still degrades after some time in the AMS, requiring the filament to be re-dried.
But that’s the “stock” AMS. There are plenty of project files to print that allow you to significantly increase the amount of desiccant that can be loaded inside, and those tweaks might address the stock configuration’s slightly-less-than-ideal performance.
