Bob, your assumptions are as good and may well be better than anyone's. For me, there is simply too much unknown to hazard any kind of guess. I think the company might be worth $5 billion if all works out on the optimistic side of reasonably well. I can't really work backwards from that, though, just a gut feel. Of all those who could (1) use Afrezza and (2) can afford it, my wild guess is 1/3 to 1/2 of them eventually will. But, again, beyond the assumption that we're approved, there is also the huge assumption that no significant competition comes along.
