In E the period number is 20 (of 24):

20
	Eb5-14	Eb5-15	Eb5-16	Eb5-17

In K the period number is its key, viz. 22 (= 7 * π):

22
	Kb3-1	Kb3-2	Kb3-3 (140)	Kb3-4	Kb3-5	Kb3-6

'A cycle is ending', is the meaning of 22 (which the reader must count to and deduce by himself). 20 is a simpler arithmetic message of the same kind: four hands are finished.

5-14 in Eb5-14 (which numbers the reader also must 'recount' for himself) alludes to fire (sun) by way of 5, and moon by way of 14, and 5 * 14 = 70 = 140 / 2. Kb3-3 has number 140, but scales of maps can be different. 5-14 could be shorthand for a sun (5) cycle (π) ending.
