This took forever to get right, but all my filament dryboxes are at 10% and I can’t get it any lower.
Perfectly dry filament, as all filament should be

Same for me

Does it make a difference? The extruder doesn't evaporate all wetness?

If there's moisture in the filament it vaporises in the extruder, causing steam bubbles that expand and disrupt the laying down of plastic, usually causing inconsistent extrusion lines (which itself causes poor layer adhesion). Some of the filament may end up being heated in the extruder slightly longer than other bits depending on these steam bubbles, which can cause overheating issues like stringing and oozing, etc..
Not to mention that filament that has absorbed water tends to become more brittle, which can lead to the filament snapping off before reaching the extruder. As a result, a filament's shelf-life is usually dictated by how quickly it absorbs moisture (and also whether UV from the sun weakens it at all, but that's a lot easier to manage).

I think 40-50% we just got off winter

What's your ambient humidity? It's usually around 80% here and I can barely get my dryboxes down to 30%
