The combat is low in intensity so I'd say it's reasonable that his army and his pools grow all the time (as do mine, but mine do it faster).
I am very sure GHC units are not all at 100% toe.
If it is low intensity, sure his armament pools might grow, but his manpower pool should drop quickly and bottom out at 20,000 to 40,000 not 170,000 and not really move.
SHC has far more armaments and manpower then they will ever use and should have 100,000's arm pts and 10,000,000 plus men by end of game and still more men in pools.
GHC Manpower pool "should" be dropping quickly and is not, SHC pools window dressing.
