I'd really like to see this kind of analysis applied to a larger sample.

If someone were to put together a little app to make this sort of data collection trivial and upload it to a central (preferably cheap) repository, would people be interested in contributing their data in exchange for analysis?

Also, since this is HN, is anyone interested in building something like this? I've got an hour or two a week of spare time to chip in.

Unrelated question, mostly for OP: do you know of any publicly available databases of GI/GL info? It's really important for people with type 1 diabetes (a subject rather dear to my heart), and could also be useful for OpenAPS stuff (https://github.com/openaps).
