You see.  I kind of understood the following chart on MP-RAS.  This is the FreeMem tab from the "Higa Charts" on an actual MP-RAS system on which I did some performance work.  (Hopefully, everyone is familiar with the Higa Charts that you can create using the views, macros and excel chart created by Larry Higa.  If not, let me know if I should write a blog about creating these charts to help get you started using these powerful tools.)
