Who the fuck programs these things? Why even have this measurement if the units are not a fixed length? Just put a light on it that says “done” or “not done”
These dryers also have a timed function that will allow to to over dry your clothes as much as you’d like. The auto modes use sensors that can detect clothes that still haven’t dried completely as they tumble about. Pretty hard to make precise unless you’re attaching sensors to every article in the dryer.
It’s an estimation, which I prefer over the vagueness of a done/not done light. I recognize that it’s not specific or reliable for any precision, but having a general idea of when it will be done is useful.
