let A := {[],[\],[X]}
let B := {appliances of the twitch card}
let I be the set of real intervals
let phi: A -> I
		 []  |-> [0, 1)
		 [\] |-> [1, 2)
		 [X] |-> [2, infinite)

let Z be a set of interpretations how strongly an aspect applies
let psi: R+  -> Z be a function for which applies:
let (a,b), (c,b) element R+
let c > a
-> psi(c) applies more strongly than psi(a)
let xi: A x B -> Z x B
		(z, b) |-> (psi(a), b) for an unknown a element phi(z)
this leaves xi not well defined, which is in nature of the problem

xi is what you were asking for
