All your points are correct and hence the center to center offset has been acknowledged by me instead of the opposite. I'm just putting forward my argument against your scrutiny.
The melting point of the Acrylic retainer is a non-issue as the pins are secured in a jig during soldering. Your scrutiny will definitely be addressed in the machining of the retainer (As you said, back to the drawing board) to cancel the offset and we'll start paying further attention in measuring each connector we make.
Of course not, Sir! The same sentiment can be put forward without the undertones.
Work event this week, with one of the better parties they've thrown (and they're all pretty good, this one at Reggie's Chicago). '80s theme party (though most of the crowd wasn't born then), with a co-worker's Tom Petty cover band, who were very good!
