Is there a way to reconcile the traditional chronology of early surahs with the biographies of Muhammad?

All the lists I have found concerning the traditional order of revelation say the first surah was Alaq (96), and the second, after the long silence, was Qalam (68). But the biographies and tafsirs I have found say that Ad-Dhuha (93) marked the end of the long silence. The lists say Ad-Dhuha was the 11th surah, not the 2nd. Is there a way to reconcile this disagreement? Is there any authority that is widely considered correct among Muslims? *Footnote*: Biographies such as "Muhammad: His Life Based on The Earliest Sources" by Martin Lings -- he draws a lot from Ibn Ishaq, although not exclusively. Tafsirs such as "[Tafhim al-Qur'an](http://www.englishtafsir.com/) " by Sayyid Abul Ala Maududi, although [Ibn Kathir](http://www.qtafsir.com) doesn't comment, as far as I can tell.
