At some point in the late evening/early morning, the elite line switches from the Chisholm call center (I believe that's where it is during the "day"?) to another line. You can tell when this has switched over because the computer no longer asks you for your WP#/PIN and they ask you over the phone. At least that's how it used to work; don't know if that changed since they installed the new automated voice system on the regular/SE line. It used to be, for me anyway, that after about midnight Central time the agents would start asking for the info rather than the computer. In fact, I called in last week about 11:30pm CDT and got what appeared to be the normal GE/PE line, so they shouldn't have switched until at least 12:30am EDT. I've found best sucess calling arount 9-10pm CDT on weeknights, or midafternoon on Saturdays if you've got an open schedule.
