More like 44-18=26 extra minutes, but, yes… you can add a “medic rinse” to a normal cycle (not Quick 30, though)— you do not have to run it separately. However, like @Reply says, it is an old model, and I have no idea what current regulations allow.
I dunno, German showers routinely have higher water pressure than American ones. Enough so that the standard fixture lets you select the volume, and many Germans routinely use less than full volume.
