Should be easy enough to verify though. Just pull any empty shot see what you get
On my machine the number 1 '100s' dip switch set to on, and all '10s' are off. That yields right around a 30ml shot depending on freshness, grind, and tamp.
I checked my settings, and you're correct. Yours seems to be set to 50ml.
Mine setting give me a 40ml single and an 80ml double without coffee.
