Hi Dan, 

There's a "download raw data" button on the side of the website at
americanredcross.github.io/OSM-Assessment. Feel free to download and play
with the data further -- and do contribute back anything new you find.
We're running more intensive stats analysis on the data now and will be
working that into the final report.

Cheers,
Robert
