  Second, we might adopt a more restrictive limit policy than Gupta and Belnap adopt.  Recall the question asked in Section 3: How should we set Sη(d) when η is a limit ordinal? We gave a partial answer: any object that is stably true [false] up to that stage should be true [false] at that stage. We also noted that for an object d ∈ D that does not stabilize up to the stage η, Gupta and Belnap 1993 allow us to set Sη(d) as either t or f. In a similar context, Herzberger 1982a and 1982b assigns the value f to the unstable objects. And Gupta originally suggested, in Gupta 1982, that unstable elements receive whatever value they received at the initial hypothesis S0.
