Yes, of course we can all see the wood for the trees now. I just wonder if
the real problem is that reading something, and comprehending what it says
are two very different things, ofthen you see and read what you expect to
se. Quite how you sort this problem out I'm not sure. I guess you use a
shadow team or something, a bit like you use multiple computers in safety
critical processes. I mean why would the human system be able to get the
right answer if it malfunctioned any more than a single computer would.
