The overlap setting should always be in [mm] e not [%]. Both in terms of infill to outer perimeter and single extrusion.

Having a [mm] unit of measure makes this setting way clearer, more universal and easier to optimize while having it in [%] makes it affected from nozzle/filament diameter, extrusion multiplier, extrusion width.

The % overlap is actually a direct percentage of the extrusion width setting. As an example lets use a 0.4mm extrusion width and a 100% allowed overlap. The 0.4mm extrusion width will be allowed to be printed 0.4mm over the existing perimeter.

The nozzle diameter only comes into play here is you are using auto extrusion width. In which case you're still shown the generated extrusion width in the extruder tab. I'll certainly note this point of confusion for our development team and see if something can be done to help with this in a future release.
