The answer to your question is as follows:
Some Ulama have prescribed the same, hence there is nothing wrong in this explanation.
إنَّمَا قَصَرَ الْأَجْزَاءَ عَلَى سِتَّةٍ وَأَرْبَعِينَ ; لِأَنَّ زَمَانَ الْوَحْيِ كَانَ ثَلَاثًا وَعِشْرِينَ سَنَةً. وَكَانَ أَوَّلَ مَا بُدِئَ بِهِ مِنَ الْوَحْيِ الرُّؤْيَا الصَّالِحَةُ، وَذَلِكَ فِي سِتَّةِ أَشْهُرٍ مِنْ سِنِيِّ الْوَحْيِ، وَنِسْبَةُ ذَلِكَ إِلَى سَائِرِهَا نِسْبَةُ جُزْءٍ إِلَى سِتَّةٍ وَأَرْبَعِينَ جُزْءًا. (مرقاۃ المفاتیح 7/2913)
And Allah knows the best
