Artillery problems in Bulge '44

[dto]

Playing the Alt 1601_s campaign in Bulge, and my German opponent is successfully using his artillery to knock out the Allied artillery. I was surprised that the Germans were winning the artillery duel, until my opponent pointed out that the Parameter data gives the Germans a 150 percent counterbattery value compared to 100 percent for the Allies, and a 125 percent indirect fire mod compared to 100 percent for the Allies.

This might make sense for the Eastern Front, but not the West in 1944, where even the Germans admitted the efficiency of Allied artillery. Is this a mistake, or should the Germans get an artillery bonus in Bulge? Also wondering about the counterbattery values in other PzC games.
