First of all. fantastic! As documented in the book _Soul of a New Machine_, Adventure plays a central role in the bring up of the DG "Eagle" / MV8000 machine. It seems to not list it (even if no copies survive) would be a gap.
You are correct they should both be using the Common Air Quality Index (CAQI). There is a new standard the EAQI and perhaps Germany has already switched to that standard.
