You're right, we should've posted the results on our previous study. I'll put those numbers together in a comprehensible format and then I'll have them posted soon.

The brief explanation of why we didn't take the time to write them up earlier is that the study was underpowered and we thought that the results weren't that informative. In retrospect, that decision was a mistake.

I've put a list of the workshop surveys that we've done in a separate comment.
