I'd like to know this, too. I am guessing it's because, if RAM errors increase linearly with the number of computers, then RAM errors will be a greater and greater proportion of total errors. This assumes other kinds of errors don't scale linearly. Someone looking through logs is looking for errors, they'd like to find fixable logic errors, not inevitable RAM errors.
