What if Pompeo's list is related to the [-21] day "countdown' in some way. And the names/things on the list that some have ciphered here are things that are to happen on those corresponding days in the "countdown".
#1 bring "Meet the IG" (i.e. DECLAS).
I took Q's [-21] to mean, like you, that we needed to watch for things happening all along the way to day 21, like you're doing with your taking note of happenings on each day.
I'd say keep a special eye on the things listed on Pompeo's list and look for stories/actions on those things.
Maybe/Maybe not.
