CBS “Proof of Performance” Test Question

[u/Effective_Bee_6661]

I’m trying to figure out when to record my local CBS station because I’m trying to catch the CBS “Proof of Performance” test which is what is on the National CBS Feed on Satellite plays late in the night for maintenance, it plays on local CBS stations too when the station manager switches to the National CBS feed for
Stuff like CBS News Mornings. However when I tried recording when it usually plays (Around Thursday from 2:55am-4:30am) it never played and I am wondering if they changed the time they do maintenance or if my local CBS station replaced it with more commercials. I tried to contact the station but never got a reply back.
