other thing I want to do is recognise all that history (that extension of my whiteboard). I want to deduct from this [2800GL] right up front, knock right off the top, what I call the volume that accounts for the history of effort. Now, if you look at some of the buyback stuff, some of the infrastructure stuff, the NVIRP 1 [Northern Victoria Irrigation Renewal Project 1] type activities. At the moment, we say that the history of effort equates to about 890GL. So that has to come off 2800 straight away -- assuming that 2800GL is the number. It might be different. bear in mind we're still testing. Work in progress. But, if it's 2800GL and 890GL, then the residual number is 1910GL. That's what's left to do. That's what I say based on the knowledge that's available to me at the moment, based on the science and based on the modelling, that's what's left to do. Between 2012 and 2019 [draws more lines]: how do we get there? The first thing I want to try and do is recognise that this should be a process of adaptation, adaptive management, recognising that we need to monitor and evaluate as we go along to see what effect we're having with this sort of volume. Because I'm a cautious sort of guy and because I want to start somewhere, I want to try and put in place a regime that will allow sensible, moderate, step processes that will allow that monitoring
