Yeh who knows whats going on but Santos has had the hole data for a while too, they'll know exactly whats going on and could probably be able to work out a reasonably accurate reserve upgrade estimate whereas i have no idea what these flow rates will do to them and i've read somewhere they are short of Gas.  They've had a long time to work out a strategy for any potential future farm-in and also as you say they've had time for a TO plan too. There could be all sorts of things going on in the background if the current flow rates are capable of and have a meaningful impact on the reserves imv.
