Gadolhadorah,
I think your approach is very good advice for a lot of goals, but I’ve found that varying wake up times (early on Monday, later on Tuesday, etc.) are hard on the body if we’re talking more than an hour difference. I daven at a hashkoma minyan on Shabbos morning, and often the latest possible davening on Sunday, especially during the summer when motzei Shabbos cleanup is late. When my Shabbos morning to Sunday morning wake up time is 2 hours different, I’ve found that I can get a nasty headache on Sunday, despite the extra rest.
