Original sentence: Kielpinski: D.Not surprising, as Bell himself has stated, "it is hard for me to believe that quantum mechanics works so nicely for inefficient practical set-ups and is yet going to fail badly when sufficient refinements are made.The possibility of this not being true comprises the fair sampling, detection, efficiency or variable detection probability loophole.While more work needs to be done, it now appears that fair sampling is a reasonable assumption and is therefore not a loophole
Edited sentence: A 260, 323-327 (1999).As Bell himself stated, "it is hard for me to believe that quantum mechanics works so nicely for inefficient practical set-ups and is yet going to fail badly when sufficient refinements are made.D 2, 1418-25 (1970).Gisin and B.Gisin, 1999: N.Gisin, A local hidden variable model of quantum correlation exploiting the detection loophole, Phys.Kielpinski, 2001: D.Pearle, 1970: P.Pearle, Hidden-Variable Example Based upon Data Rejection, Phys.The possibility of this not being true comprises the fair sampling, detection, efficiency or variable detection probability loophole (Pearle, 1970; Gisin, 1999).Though, as the authors themselves recognise, the "locality" loophole was open in this experiment, it is believed by many physicists to show that fair sampling is a reasonable assumption and therefore not a loophole
