I went ahead and plotted my values, and there isn't a strong correlation yet between duration of sleep and steps, probably because some days I have to wake early for work, but on most days I can sleep in. However, a pattern is emerging between steps in a day and bedtime that night. My graph results show that if I get less than 5000 steps, I'm much more likely to stay up past 1am. None of my high-step days had a bedtime of past 1am.
I have sleep-onset insomnia, and I'm trying to get to bed earlier (before midnight, preferably). Being more active during the day really helps, which is a challenge on days when I work on the computer from home. It helps when I'm traveling for work. You can see the stats and graphs on my Google Drive Sheet below. The data is really diverse because of so many outliers, like the day I got lots of steps, but then got food poisoning, so I had little sleep. Or the day I got lots of steps but had to wake up super early. And a few days of low steps but high sleep duration that night, because I was so sleep-deprived from getting up really early the days before (while having food poisoning), that I was playing catchup.
My conclusion is that steps is a better predictor of bedtime for me than of sleep duration.
