I have not seen anything with stats on PACE. It is only in its third year I think?
There is a page on the UT website that has all kinds of great data. I have not seen what you are looking for on the CAP program which makes me wonder if they will ever have that detail for PACE.

I would think if you follow the guidelines for McCombs internal transfer you’d be in pretty good shape because that is pretty similar to what you are doing.
