"Usually, when you are hit, you can't move very well because the knockback pushes you off the ground into the air. But you never left the ground so PM_WalkMove() applies instead of PM_AirMove(). You can walk on the ground with typical air acceleration. I guess that they removed the PMF_TIME_KNOCKBACK from this if() statement in CPM which would make the effect 10 times stronger than in VQ3. Feels right when I do so."
WOAH 10 TIMES SHTRONGER!
