RE: Going the distance

In reply to:
The latter is simply not a tolerable situation
to me.  It's simple math, if you want 10,000,000 trouble free
installations, then you're going to have to ensure that the
one-in-a-million combination of worst-case devices still works.

Is there really *any* other way to go about this?

Yes there is.  Its called statistics.  Instead of designing for worst case, 
you design for 3 sigma, or 5 sigma, or whatever.  It makes a lot more sense 
even if you are designing atom bombs.  Well, ok, maybe worst case is 
necessary for that one.............
