What was the daily Quranic amount that Ibn Mas'ud used to recite when completing the Quran in a week and in three days?

Ibn Mas'ud used to complete the recitation of the Qur'an in a week and three days, and sometimes from Friday to Friday outside of Ramadan. It is authentically reported from him, as well as from 'Uthman and Tamim al-Dari, that they used to complete it in seven days. There is no specific measure for daily recitation reported; it depends on the reader's activity and commitments.
