Need to point out the Q map graphic does not have post #s like you quoted.
If has 8chn post numbers.
However, when considering what control item Q team could use
They can control when they post (time, h:m:s) and harder to target (seconds)
Therefore map decoding can only use time stamps and dates against the Post questionz/lines.
Ans we have been shown to sind the clock backwards more than once.
