I think you folks are being to hard on Al Wick.  He apparently 
makes his living doing risk analysis; and like the workman 
who has only one tool - say, a hammer - everything looks 
like a nail.  The problem with his analysis is the same as 
with all statistical analysis: (1) how one selects the data 
to be used, (2) grouping unlike samples together, and (3) 
generalizing from too small a sample.

Since - at this point - every installation is in some way 
unique, the failure *rates* are meaningless.  One can pretty 
much ignore his pronouncements - except as they apply to 
specific components, rather than the whole system.
