Keep in mind that $850 is cheaper than your copay plus the value of your mileage award miles. So if you end up having to wait until a few hours before flight to get the u/g, while you won't have the security of having it in advance, you'll actually save some money. And yes, you should keep checking. When you saw R=2 you could have called and possibly snared it.
