Locked in?

Also, I haven't see any reliable information to the effect that accelerometer-based inferences are comparable to the Zeo's electrode recording.

Yes, locked in. When I was using the Zeo, all of your data lived on their flash based site, and there was no obvious way to get it out and into your own analytic tools.

Also, for purposes of managing sleep hygiene, you don't need highly accurate records. Moderately accurate data will benefit most individuals with imperfect sleep hygiene.

Perhaps it's a new functionality, but their site currently offers data export to CSV.

They've had CSV export ever since I began using it, and I've never had major problems with that - it's what I use for my statistics in R. Since around when I got one, they even have firmware that supports sending out the raw data second by second over a serial cable (which I was thinking about using for meditation).

So I figure either stcredzero used Zeo a long time ago, or he simply didn't know about the options.
