Mike, There's 30 years of Papers and discussions on how to do Capacity Planning for MVS.
The answer is far more complex than the simplicity of your question. Averages or peaks? What about percentiles and omission of outliers? A quick Google shows there are courses (Guerilla Capacity Planning), many red books, and articles that you can download or buy (Capacity Planning for MVS 1979:Artis). You may find some better answers than "it depends" in amongst the 30 years of flotsam and jetsam on floating around the internet.
