DBMM: IV/73 Ming allies for IV/78 Yi Korean?

Although the DBMM list for IV/78 Yi Dynasty Korean allows for IV/73 Ming Chinese Allies, after 1420 the latter only have one troop type with a non-0 minimum. In other words, only that single troop type can be used as allies.



So, would only 3 elements of Chinese mercenary cavalry, plus one general, be all that an allied Ming contingent could provide???
