When performing your air swings, be sure that you are not moving your head/eyes during your forward swing -- it might be that your bad day is due to excessive head movement during your strokes.
Jumping rope on changeovers sometimes helps. During rallies, try the BOUNCE-HIT mantra.
My bad days have almost always been due to inadequate sleep the prior nite.
