Or a better way to word that question: Because it's hard to be exact, is it better to cut a cycle off, or go 5 minutes or so into the next cycle?
Thanks a ton
It's closer to the 105 answer, but this will obviously depend on the actual length of your cycle (90 minutes is just an average; everyone varies a little) as well as the time it takes you to get to sleep.
In my case, my cycle length is nearer 80 minutes; and it usually takes 10 minutes or less to get to sleep. I set the alarm for about 100 minutes (so there's a bit of a buffer there, just in case), but I usually wake up before it goes off.
As to the second point, I prefer to go 5 minutes into the next cycle (if there's any deviation at all) - much more refreshing than not quite having enough sleep.
