Does DYS compile the information from the DYS members and do anything with it?

I think it would be really interesting to know how many kids skip a grade, how many are able to make school work, how many homeschool, etc.

I'd guess there would need to be some sort of permission on their yearly data collection efforts, but it seems to me the information would be worthwhile to the community.

Does it already exist? Anyone else think it would be worthwhile to have this info?
