You can over do it. I'd rather stick to my training on TCAS and follow the guidance on the EADI which would not put anyone into 0 G's, nor stress the airframe and possibly kill everyone by breaking the plane. I would only over do it if I had to by SEEING the plane and NEEDING to avoid it. TCAS should prevent that from happening. I have at least one TCAS event per month flying in the NY area.
