Your new 8 hour Sleep is quite advanced and seems to be working. But I am really curious how you developed it. As you mention in the introduction, sleep patterns change as you get older, so could there be different versions for different age groups?
This is just my personal opinion, but after childhood, the quality of our sleep really goes downhill! The "Senior" sleep pattern is a dirty mess, nobody would find that restful or restorative.
