Not 48 , I don’t actually keep track but it feels 12 hours when I have time, I wake up around 6 and after breakfast and dailies, I start around 7 am and go until 8 pm but I stop to do other things in between and sometimes I push it to 10. It depends on luck, in a lucky day I remember getting 25 deeds just in the morning so around 5 hours and in bad days less than 20 during 12, 14 hours. So in average, it would be 25 deeds per day of 12 hours, a book in 24 hours.
