1 in 10 may mathematically meet the definition of "not likely", but it
isn't /that/ unlikely in terms of likelihoods humans deal with just
crossing the street. Working on the basis of assuming we'll need to
complete 50%-90% before we're "done" merely puts our guesstimates in the
realm of where we're not being overly hopeful. RC5-72 may be done on the
first day, but I'd be much less disgruntled if I expected it to take a few
years. Remember, Murphy would have loved computers.
Programming is a Dark Art, and it will always be. The programmer is
fighting against the two most destructive forces in the universe:
entropy and human stupidity. They're not things you can always
overcome with a "methodology" or on a schedule.
