I am interested in this answer. I would assume that the time frame would be the same but who knows for sure.
In a busy world practice of any kind is hard to come by. I'm on level 1 and practice when I can but practice every day for 40 to 70 minutes depending. I am on day 15 and have not missed a day. Sometimes it is 10 at night; sometimes it is 7 in the morning. For me the important thing is to practice every day. With holiday stuff, kids school concerts and other family and work obligations things get a little harried but it gets done. That is, ultimately, the important part.
