If anyone else is interested in them, I'm willing to score, count, and/or categorize the responses to the "Changes in Routine" and "What Different" questions.

However, I've started to try and develop a scheme for the former... and I've hit twenty different categories (counting subcategories) and will probably end up with 5-10 more if I don't prune them down.

What sort of things do you think might be interesting to look for?

(Though I haven't started to do work on paper, the latter seems like a much simpler problem. However, if you have thoughts on the selection of bins, please share them.)

(As a note: I would be able to modify the .xls or such, but some one else would have to do the stats; I haven't developed practical skills in that field yet, so the turnaround time would be awful.)
