Default Lazy / slow o2 sensors at idle

I have fairly new vette rear o2 sensors in my LT headers. Im just wondering how lazy the o2 sensors should be at idle? When I first come to a stoplight, i might get 3 or 4 seconds pegged rich or lean before the sensors start swinging nicely, albeit not as quickly as at cruise. What is the preferred method to liven up the o2s at idle? Closed loop proportional idle bas vs. airflow? Or Closed loop proportional idle gain vs. o2 error?

Also, would this have any bearing on low rpm bucking? Im guessing that it could make your VE table inaccurate and cause bucking.
