In the first chart, how do the midnight times relate to each other? If I see a dot slightly before midnight on Column N (near the top), then dots around 1:00 and 4:00 in Column N+1 (near the bottom), does that represent a bed/wake/bed cycle?
I think confusion around 24 hour days and "sleep days" are probably the source of your sub 3 hour sleeps. Those pngs are really small, but it looks like early Nov-09 might have had some days where you slept early-ish, woke up shortly after midnight and then didn't get to bed until after midnight the next night.
I'd extend that question to your daily average as well. With the iregularity of your insomnia, adding up sleep in a midnight-midnight 24 hour period doesn't seem like a good fit. I'd love to see if the data changes if you just switch the day limits to noon-noon.
