Just a summary (in no particular order) of delta theories (where to look on the clock):

4M There is a table of relevant markers that are revealed in the horizontal and vertical axis reflections of the “active” marker.

55L The relevant post is the natural mirror (:30 minutes away) or the marker reflected in the :55 line (Q line from :55 to :25) from the “active” marker. More specifically the post from 3 rotations ago is the important one.

3D The “active” marker has relevant posts at :05 :10 and :15 markers away from it. See Q post 455 (KEK 5 by 5).

111D The relevant marker is the one that was 111 days (markers) ago

23P The relevant posts are a :23 delta (pain) theory (+/-).

KL The KEY LINES active marker has to be mirrored in one of the KEY lines (expansion on 23P) KEYS are Q17[Q line] P23[pain line] D5(45 [potus line]) (additional suggestions BA44 [bombs away] CC55 [comms clear]

KEY KEYSTONE theory (important markers are determined by overlaying a keystone image on the clock).

Compiled from various ClockFag theories and testing. Active post could be the most recent or one indicated by a POTUS tweet. That is an entirely different post.
