This identification is seemingly rejected by Baker who makes no mention of any attestion for Neferkare II beyond the Abydos king list, while Thomas Schneider relates Wadjkare to either Neferkare II or Neferirkare II.
Baker does not support the identification, citing only the Abydos king list for Neferkare II. In contrast, Thomas Schneider links Wadjkare to both Neferkare II and Neferirkare II.
