(S+- = Z-+) + (S-+ = Z+-) == (N = 5/8 with 1/2 return to S and Z) (S+ = Z-) + (S- = Z+) == (N = 5/16) 5/8 return is exponential as carrier pulse (through resonance) between S and Z. 5/8 is the off-set of centre, relative to carrier pulse, in either positive or negative application, which reflects the positive and negative relationship (within directional arc) between S and Z. These sides are nominally disproportionate, as is necessary by the nature of propogation within a macrocosm/microcosm environment (they need to be directional). Off-setting 5/8 in one direction may promote/amplify the resonance, or oppose/cancel it, depending on the timing which is used 5/16 is balanced of centre, without return. Return is equated as fractional recurrence either side of N (0.5), relative to the (half) exponential (half) return relationship between S and Z 5/16 = (-+5.5+- (5) +-5.5-+). Which is exactly equal to the resonant exchange between S and Z (making it stable)
