I was wondering how many of these aptly named hilbert problems proposed by baseball prospectus have been solved?

Any help is greatly appreciated

Solved? None of them. There have been good starts made on some of them, especially #7, but for the most part we’re not much further along.

Thats what I had thought since I haven’t seen a whole lot about any of those ideas.  Thanks for the info
