The usual nuclear recoil energy reconstruction employed by liquid xenon dark matter search experiments relies only on the primary scintillation photon signal .
Energy reconstruction based on both the photon and electron signals yields a more accurate representation of search results .
For a dark matter particle mass m _ { \chi } \sim 10 GeV , a nuclear recoil from a scattering event is more likely to be observed in the lower left corner of the typical search box , rather than near the nuclear recoil calibration centroid .
In this region of the search box , the actual nuclear recoil energies are smaller than the usual energy scale suggests , by about a factor \times 2 .
Recent search results from the XENON100 experiment are discussed in light of these considerations .
