I've been sleeping biphasicly (is that a word?) for about ten days now with no real problems (except when I forget to change the PMs to AMs on my alarm) but I was having some trouble optimizing my time schedule and figuring out what time would be best for core sleep with my nap at time xx:xx. I read that 6.5 hours was a good amount of time after the nap and before the core sleep. I made a chart in excel based on this concept because if you're anything like me adding and subtracting times in your head can get a little confusing, so this is useful for a quick reference.
For Example, if I want to take my nap at 5pm I can look at the chart and it will tell me what time to take my core sleep and wake up the next day. It works backwards too. If you know you want to wake up at 5:30am you can look at the chart and it will tell you what time to take your nap.
I also know that 6.5 hours between naps isn't optimal for everyone so I made it so you can change one of the cells in the spreadsheet to reflect the amount of time you want in between your naps.
It's a simple spreadsheet, and it only took me about 10 minutes to make. I'd be happy to share it with anyone else who would like to use it.
