IMO MP rounds don't pay off for easy points.
It takes much more time than a single round, and there's always the danger of a disconnection, be it voluntary or by force majeur.
Also, the XP outcome seems less than - say - two single tourney rounds of strokeplay.
How many XPs are there for a 2.5 hour fourball? More than 940 (400+400+70+70)?
The easiest way will be only to rely on the CDP bonus. A CTTH or one or three holes per day, that passes quickly, 880+ points in a few minutes.
