I'm a know-nothing but my guess would be that only an 
experiment would tell you the answer. Listen to something
that stays in one place, like a cricket or tree frog 
chirping, and then try different mic positions.

this because I've been trying to use a test tube clamp in order to 
hold the mics in place (micS because I'm also doing experiments with 
the Sony ECM-MS957 stereo mic), but this clamp is not able to make 
the mic point precisely to the center of the "pseudo-parabola".
