    I was hoping he was just having a few typo's and would catch it...

    Superheat for fixed orifice.

    Subcooling (and sometimes superheat) on TXV.

    Many things work... That does not make it right.. There are too many unknown variables in your situation to explain why it is working.. But according to the manufacturers, superheat for fixed and subcool for TXV.
