In 2015 based upon analysis of other manuscripts not explored by previous researchers, professor of African history Mauro Nobili and others argued that the work published by Houdas and Delafosse is in fact a conflation of two separate works, that he names the Tarikh Ibn al-Mukhtar, being the chronicle written by Ibn al-Mukhtar, and the actual Tarikh al-fattash, being Appendix 2 of Houdas' and Delafosse's Chronique de Chercher and called the Notice Historique by professor Paulo Fernando de Moraes Farias in earlier work from 2008 plus the text of MS A and MS B used by Houdas and Delafosse.[14][15][16]
