Actually, I have to correct myself...
In the meantime, while subsim forum was down yet again - I had just posted the post above, when the forum wouldn't update, so I checked listening to the video yet again, and I think I got it wrong, sorry...
He said "vierten Drittel" that is the 4th "third" as in the 3rd month. I just thought I heard something else, or perhaps I wanted to hear something else, so I got so excited that I just had to post it, and then when I wanted to edit my post.... BOOM off the forum went again.
