Hi James, do you have the Vedic book "Dwadashottari Dasha" by R.S. Panwar....if so see page 71 where he says...."In dasamasa, Moon is in 10th House....".
I'm not getting Moon in 10th are you? Also I take it this system uses Lahiri ayanamsha.
P.S: this example is for a man born Oct 11, 1942, 16:00 Hours in Allahabad, India.
