AFAIK, CFSIZER only gives sizes for the individual structures.

I would expect the answer to be "it depends" (on the level of CFCC LIC code you 
are running).  I would expect the answers from CFSIZER and advice on the 
webpage would ensure proper sizing so that you have enough storage for the 
structures, the structure controls, dump space and the underlying control code.
