(1) max rel. mismatch Phi vs factor*Omega over 2000 random (s,r) in [e^-3,e^3]^2: 2.27e-13
(2) max rel. mismatch h vs Bose-integral formula on 12 random arc points: 1.15e-08
(3) 2-move arcs tested: 300; arcs with a negative second difference (tol 1e-12*max|h|): 0; min normalized 2nd diff 2.01e-22
(4) k=2: 3000 random feasible chains, max (Phi-G)/G = -1.231e-05
(4) k=3: 1269 random feasible chains, max (Phi-G)/G = -3.455e-03
