<t>I found 0,398 with probabity calculus.The max for d(C1,C2) is 2r and for d(S1,S2) it is sqrt(2*Pi)*r.Where r is the radius of the circle.Minimums are both 0.IMO d(C1,C2) and d(S1,S2) are both uniform (but not on the same interval).My calcul is P(d(S1,S2)< E(d(C1,C2)))= 1/sqrt(2Pi)where E(d(C1,C2)...
