Gee, and I searched through every thread in this forum before posting.
Actually, I never would have thought to look in the LH Forum for information about Sixt. After your post, I did a search and came up with 305 hits on various forums -- but no way to know which just mentioned Sixt in passing and which gave the information about its status levels.
That is why TalkBoard voted to recommend that Randy start this forum -- to make it easier to find info like this.
