Qingming He from Xi'an Jiaotong University points out, correctly, that analog tallies for certain scores will not work correctly when survival biasing is turned on. The specific cases he mentioned is (n,xn) tallies (since it relies on wgt/last_wgt) and the scattering rate, where the scoring weight is not reduced by the fraction absorbed.
