Clockfag Theories on Mirrors
Just a summary (in no particular order).
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.
Here is a clock for tomorrow's marker. From the previous wind.
