Swh. You obviously haven’t caught on to the reality of CoS18, what happened with Oasis has naff all to do with it.
The KA freighter guys did their initial 400 rating with CX while they were still KA. When CX took over they only had to do a PC and 4 sectors, it was a rapid command not a full CX command course.
There is a big difference between having MFF in the manuals and putting it into practice.
